Track-list worked but with a flash. +**Why cover-grid failed**: `visibilityChanged` fires BEFORE `_finishDOMUpdate` updates the sizer. So `scrollHeight` reflects the PREVIOUS state (premature layout with scrollSize=1). The guard `scrollHeight <= clientHeight` was always true during the visibilityChanged handler, causing every event to be skipped. Only after a manual scroll (which triggers a fresh `visibilityChanged` with updated DOM state) did it work. +**Why track-list flashed**: `layoutComplete` uses internal double-rAF, so the scroll happens 2 frames after the initial render at position 0. + +### Approach 5: `visibilityChanged` + `scrollHeight > clientHeight` guard removed + `layoutComplete?.then` + `scrollToIndex` +**Result**: Cover-grid worked but with flash. Track-list worked but with flash. +**Why it flashed**: The double-rAF delay in `layoutComplete` means 2 frames render at position 0 before scrolling. + +### Approach 6: `visibilityChanged` + `requestAnimationFrame` + `scrollToIndex` (no guard for cover-grid) +**Result**: Track-list worked without flash. Cover-grid did not work at all. +**Why track-list worked**: Flow layout has real items immediately. rAF fires after sizer is set. `scrollToIndex` works. +**Why cover-grid failed**: First `visibilityChanged` is premature (0 columns). `hasRestoredScroll` set to true. rAF fires, but grid still has 0 columns → pin fails. Restore opportunity consumed. + +### Approach 7: `visibilityChanged` + `last <= 0` guard for cover-grid + `requestAnimationFrame` + `scrollToIndex` +**Result**: Track-list worked without flash. Cover-grid did not work. +**Why cover-grid failed**: The `last <= 0` guard correctly skips the premature event. The second `visibilityChanged` (real layout, `last > 0`) triggers the handler. `hasRestoredScroll = true`, schedules rAF. But in the rAF callback, `scrollToIndex` → pin → reflow → `_sizeHostElement` + `_correctScrollError` → `scrollTo`. The sizer was updated in `_finishDOMUpdate` (same JS execution context as the `visibilityChanged`), but the browser hasn't processed it into `scrollHeight` yet when `scrollTo` is called inside the pin-triggered reflow. The `scrollTo` is clamped to the old (small) scrollHeight. + +**Key insight**: For cover-grid, even after waiting for the real `visibilityChanged`, the pin mechanism's synchronous reflow chain does `_sizeHostElement` + `scrollTo` atomically. The browser never gets a chance to process the sizer into `scrollHeight` between these two operations. This is why `requestAnimationFrame` alone isn't enough for cover-grid — the problem isn't WHEN we call `scrollToIndex`, it's that `scrollToIndex`'s internal reflow always does sizer+scroll atomically. + +## Current State of Code + +The current code has: +- `track-list.ts`: `visibilityChanged` handler with `requestAnimationFrame` + `scrollToIndex` (works without flash) +- `cover-grid.ts`: `visibilityChanged` handler with `last <= 0` guard + `requestAnimationFrame` + `scrollToIndex` (does NOT work) + +## Untried Ideas + +1. **Bypass `scrollToIndex` entirely for cover-grid**: After `layoutComplete` resolves (sizer is painted), directly set `el.scrollTop` instead of `scrollToIndex`. This avoids the pin mechanism's atomic sizer+scroll problem. The virtualizer will react to the scroll event and re-render items at the new position. + +2. **Use `scrollToIndex` on the SECOND `visibilityChanged` after the real one**: The first real `visibilityChanged` triggers `_finishDOMUpdate` which sets the sizer. After the browser paints (next frame), `scrollHeight` is correct. If we could delay to the next `visibilityChanged`... but there might not be one without user interaction. + +3. **Pre-set the pin before the virtualizer initializes**: If we could inject the pin into the layout before the first `_updateLayout` runs, the virtualizer would start at the correct position. But the layout's pin setter is internal. + +4. **Use `element(index).scrollIntoView()` when the item IS in range**: After `layoutComplete`, if the target item happens to be in the rendered range, native `scrollIntoView` works. But for distant items it won't be in range. + +5. **Two-phase for cover-grid**: Use `layoutComplete?.then` to wait for sizer to be painted, then set `scrollTop` directly (not `scrollToIndex`). Calculate pixel offset: `offset = padding + Math.floor(index / columns) * (itemHeight + gap)`. Grid config is known: `itemSize: 230px height, gap: 16px, padding: 16px`. Columns can be derived from viewport width: `columns = Math.floor((viewportWidth - padding*2 + gap) / (itemWidth + gap))`. This is fragile but would work. + +6. **For cover-grid, after `layoutComplete` resolves, use `requestAnimationFrame` + direct `scrollTop`**: `layoutComplete` ensures sizer is painted → `scrollHeight` is correct. Then rAF + `el.scrollTop = computedOffset` avoids the pin mechanism entirely. The virtualizer reacts to the scroll event. + +7. **Hybrid approach**: Track-list uses `requestAnimationFrame` + `scrollToIndex` (works). Cover-grid uses `layoutComplete?.then` + direct `scrollTop` (avoids pin, avoids flash since we set scrollTop before paint in the rAF following layoutComplete... actually layoutComplete already used double-rAF so there would still be a flash). + +## File Locations + +- `frontend/src/store/library-store.ts` — LibraryStore singleton +- `frontend/src/store/controllers/library-controller.ts` — LibraryController +- `frontend/src/components/track-list/track-list.ts` — Track list component +- `frontend/src/components/cover-grid/cover-grid.ts` — Cover grid component +- `frontend/src/events.ts` — Frontend event constants +- `backend/events/events.go` — Backend event constants +- `backend/library/library.go` — Emits LibraryScanComplete +- `frontend/node_modules/@lit-labs/virtualizer/` — Virtualizer source (v2.1.1) diff --git a/backend/database/sql/queries/release_groups.sql b/backend/database/sql/queries/release_groups.sql index 7e59491..a0ace65 100644 --- a/backend/database/sql/queries/release_groups.sql +++ b/backend/database/sql/queries/release_groups.sql @@ -43,13 +43,20 @@ SELECT * FROM release_groups ORDER BY name; -- name: GetAllAlbumsWithDetails :many -SELECT +SELECT rg.id, rg.name, rg.year, - COALESCE(ac.text, '') as artist_name, + COALESCE(ac.text, fallback_ac.text, '') as artist_name, COALESCE(ca.file_path, '') as cover_art_path FROM release_groups rg LEFT JOIN artist_credit ac ON rg.album_artist_credit_id = ac.id LEFT JOIN cover_art ca ON rg.cover_art_id = ca.id +LEFT JOIN ( + SELECT rgr.release_group_id, ac2.text + FROM release_group_recordings rgr + JOIN recordings rec ON rec.id = rgr.recording_id + JOIN artist_credit ac2 ON ac2.id = rec.artist_credit_id + GROUP BY rgr.release_group_id +) fallback_ac ON fallback_ac.release_group_id = rg.id ORDER BY rg.name; diff --git a/backend/database/sql/sqlcgen/release_groups.sql.go b/backend/database/sql/sqlcgen/release_groups.sql.go index f765973..6e8a236 100644 --- a/backend/database/sql/sqlcgen/release_groups.sql.go +++ b/backend/database/sql/sqlcgen/release_groups.sql.go @@ -79,15 +79,22 @@ func (q *Queries) DeleteReleaseGroup(ctx context.Context, id int64) error { } const getAllAlbumsWithDetails = `-- name: GetAllAlbumsWithDetails :many -SELECT +SELECT rg.id, rg.name, rg.year, - COALESCE(ac.text, '') as artist_name, + COALESCE(ac.text, fallback_ac.text, '') as artist_name, COALESCE(ca.file_path, '') as cover_art_path FROM release_groups rg LEFT JOIN artist_credit ac ON rg.album_artist_credit_id = ac.id LEFT JOIN cover_art ca ON rg.cover_art_id = ca.id +LEFT JOIN ( + SELECT rgr.release_group_id, ac2.text + FROM release_group_recordings rgr + JOIN recordings rec ON rec.id = rgr.recording_id + JOIN artist_credit ac2 ON ac2.id = rec.artist_credit_id + GROUP BY rgr.release_group_id +) fallback_ac ON fallback_ac.release_group_id = rg.id ORDER BY rg.name ` diff --git a/backend/events/events.go b/backend/events/events.go index 3e75157..3462a7d 100644 --- a/backend/events/events.go +++ b/backend/events/events.go @@ -49,3 +49,8 @@ const ( const ( LibraryConfigChanged = "LibraryConfigChanged" ) + +// Library events. +const ( + LibraryScanComplete = "LibraryScanComplete" +) diff --git a/backend/library/library.go b/backend/library/library.go index a6bf945..63d729f 100644 --- a/backend/library/library.go +++ b/backend/library/library.go @@ -335,6 +335,8 @@ func (l *Library) Scan() error { "library", l.conf.DirectoryPath, ) + runtime.EventsEmit(l.ctx, events.LibraryScanComplete) + return scanErr } @@ -510,18 +512,27 @@ func (l *Library) processMetadata(result importResult) (int64, error) { }) } - // 3.

Paint - -## What Has Been Tried - -### Approach 1: `scrollTop` pixel offset with `await updateComplete` + double-rAF -**Result**: Failed for both components. -**Why**: `await this.updateComplete` only waits for the parent Lit component's render. The `LitVirtualizer` child element exists in the DOM but hasn't completed its own Lit render cycle — the `Virtualizer` instance doesn't exist yet. The double-rAF fires too early. - -### Approach 2: `scrollTop` pixel offset with `await updateComplete` + `await layoutComplete` -**Result**: Failed for both components. -**Why**: After `await this.updateComplete`, `this.virtualizer.layoutComplete` returns `undefined` because `virtualizerRef` hasn't been set yet (LitVirtualizer hasn't rendered). `await undefined` resolves immediately. - -### Approach 3: Index-based save/restore via `visibilityChanged` event + immediate `scrollToIndex` -**Result**: Track-list worked. Cover-grid did not. -**Why track-list worked**: Flow layout has real items on first `visibilityChanged`. `scrollToIndex` sets a pin, the reflow works correctly. -**Why cover-grid failed**: First `visibilityChanged` is premature (0 columns). `scrollToIndex` sets pin, but reflow with 0 columns produces garbage positions (division by 0). - -### Approach 4: `visibilityChanged` + `scrollHeight > clientHeight` guard + `layoutComplete?.then` + `scrollToIndex` -**Result**: Cover-grid partially worked (scrolled to correct position after one manual scroll, not on initial load). Track-list worked but with a flash. -**Why cover-grid failed**: `visibilityChanged` fires BEFORE `_finishDOMUpdate` updates the sizer. So `scrollHeight` reflects the PREVIOUS state (premature layout with scrollSize=1). The guard `scrollHeight <= clientHeight` was always true during the visibilityChanged handler, causing every event to be skipped. Only after a manual scroll (which triggers a fresh `visibilityChanged` with updated DOM state) did it work. -**Why track-list flashed**: `layoutComplete` uses internal double-rAF, so the scroll happens 2 frames after the initial render at position 0. - -### Approach 5: `visibilityChanged` + `scrollHeight > clientHeight` guard removed + `layoutComplete?.then` + `scrollToIndex` -**Result**: Cover-grid worked but with flash. Track-list worked but with flash. -**Why it flashed**: The double-rAF delay in `layoutComplete` means 2 frames render at position 0 before scrolling. - -### Approach 6: `visibilityChanged` + `requestAnimationFrame` + `scrollToIndex` (no guard for cover-grid) -**Result**: Track-list worked without flash. Cover-grid did not work at all. -**Why track-list worked**: Flow layout has real items immediately. rAF fires after sizer is set. `scrollToIndex` works. -**Why cover-grid failed**: First `visibilityChanged` is premature (0 columns). `hasRestoredScroll` set to true. rAF fires, but grid still has 0 columns → pin fails. Restore opportunity consumed. - -### Approach 7: `visibilityChanged` + `last <= 0` guard for cover-grid + `requestAnimationFrame` + `scrollToIndex` -**Result**: Track-list worked without flash. Cover-grid did not work. -**Why cover-grid failed**: The `last <= 0` guard correctly skips the premature event. The second `visibilityChanged` (real layout, `last > 0`) triggers the handler. `hasRestoredScroll = true`, schedules rAF. But in the rAF callback, `scrollToIndex` → pin → reflow → `_sizeHostElement` + `_correctScrollError` → `scrollTo`. The sizer was updated in `_finishDOMUpdate` (same JS execution context as the `visibilityChanged`), but the browser hasn't processed it into `scrollHeight` yet when `scrollTo` is called inside the pin-triggered reflow. The `scrollTo` is clamped to the old (small) scrollHeight. - -**Key insight**: For cover-grid, even after waiting for the real `visibilityChanged`, the pin mechanism's synchronous reflow chain does `_sizeHostElement` + `scrollTo` atomically. The browser never gets a chance to process the sizer into `scrollHeight` between these two operations. This is why `requestAnimationFrame` alone isn't enough for cover-grid — the problem isn't WHEN we call `scrollToIndex`, it's that `scrollToIndex`'s internal reflow always does sizer+scroll atomically. - -## Current State of Code - -The current code has: -- `track-list.ts`: `visibilityChanged` handler with `requestAnimationFrame` + `scrollToIndex` (works without flash) -- `cover-grid.ts`: `visibilityChanged` handler with `last <= 0` guard + `requestAnimationFrame` + `scrollToIndex` (does NOT work) - -## Untried Ideas - -1. **Bypass `scrollToIndex` entirely for cover-grid**: After `layoutComplete` resolves (sizer is painted), directly set `el.scrollTop` instead of `scrollToIndex`. This avoids the pin mechanism's atomic sizer+scroll problem. The virtualizer will react to the scroll event and re-render items at the new position. - -2. **Use `scrollToIndex` on the SECOND `visibilityChanged` after the real one**: The first real `visibilityChanged` triggers `_finishDOMUpdate` which sets the sizer. After the browser paints (next frame), `scrollHeight` is correct. If we could delay to the next `visibilityChanged`... but there might not be one without user interaction. - -3. **Pre-set the pin before the virtualizer initializes**: If we could inject the pin into the layout before the first `_updateLayout` runs, the virtualizer would start at the correct position. But the layout's pin setter is internal. - -4. **Use `element(index).scrollIntoView()` when the item IS in range**: After `layoutComplete`, if the target item happens to be in the rendered range, native `scrollIntoView` works. But for distant items it won't be in range. - -5. **Two-phase for cover-grid**: Use `layoutComplete?.then` to wait for sizer to be painted, then set `scrollTop` directly (not `scrollToIndex`). Calculate pixel offset: `offset = padding + Math.floor(index / columns) * (itemHeight + gap)`. Grid config is known: `itemSize: 230px height, gap: 16px, padding: 16px`. Columns can be derived from viewport width: `columns = Math.floor((viewportWidth - padding*2 + gap) / (itemWidth + gap))`. This is fragile but would work. - -6. **For cover-grid, after `layoutComplete` resolves, use `requestAnimationFrame` + direct `scrollTop`**: `layoutComplete` ensures sizer is painted → `scrollHeight` is correct. Then rAF + `el.scrollTop = computedOffset` avoids the pin mechanism entirely. The virtualizer reacts to the scroll event. - -7. **Hybrid approach**: Track-list uses `requestAnimationFrame` + `scrollToIndex` (works). Cover-grid uses `layoutComplete?.then` + direct `scrollTop` (avoids pin, avoids flash since we set scrollTop before paint in the rAF following layoutComplete... actually layoutComplete already used double-rAF so there would still be a flash). - -## File Locations - -- `frontend/src/store/library-store.ts` — LibraryStore singleton -- `frontend/src/store/controllers/library-controller.ts` — LibraryController -- `frontend/src/components/track-list/track-list.ts` — Track list component -- `frontend/src/components/cover-grid/cover-grid.ts` — Cover grid component -- `frontend/src/events.ts` — Frontend event constants -- `backend/events/events.go` — Backend event constants -- `backend/library/library.go` — Emits LibraryScanComplete -- `frontend/node_modules/@lit-labs/virtualizer/` — Virtualizer source (v2.1.1) diff --git a/backend/library/coverart.go b/backend/library/coverart.go index 1e1cbfc..e39cdca 100644 --- a/backend/library/coverart.go +++ b/backend/library/coverart.go @@ -18,42 +18,75 @@ import ( "yellowjacket/backend/system" ) -const ( - // thumbnailMaxSize is the maximum width/height for generated thumbnails. - thumbnailMaxSize = 200 - // thumbnailQuality is the JPEG encoding quality for thumbnails. - thumbnailQuality = 80 - // thumbnailSuffix is appended to the content hash for thumbnail filenames. - thumbnailSuffix = "_thumb" -) +// thumbnailTier defines a single size tier for generated cover art thumbnails. +type thumbnailTier struct { + // Suffix appended to the content hash (e.g. "_sm", "_md", "_lg"). + Suffix string + // MaxSize is the maximum width or height in pixels. + MaxSize int + // Quality is the JPEG encoding quality (1-100). + Quality int +} + +// thumbnailTiers lists all generated size variants, ordered smallest to largest. +var thumbnailTiers = []thumbnailTier{ + {Suffix: "_sm", MaxSize: 100, Quality: 75}, + {Suffix: "_md", MaxSize: 200, Quality: 80}, + {Suffix: "_lg", MaxSize: 400, Quality: 85}, +} + +// legacyThumbSuffix is the old single-thumbnail suffix used before the +// multi-tier system.

The button clears all tracks from the queue, stops playback, and resets queue state. - -## Architecture Overview -The backend already has a `Queue.Clear()` method (`backend/queue/queue.go:1540`) that handles everything — clearing tracks, stopping playback, resetting state, persisting, and emitting `QueueChanged`. The only missing piece is wiring it to the frontend via the event system and adding the UI button. - -## Changes Required (5 files) - -### 1. `backend/events/events.go` — Add new event constant -Add `RequestClearQueue` to the queue events const block. - -```go - RequestMoveQueueTracks = "RequestMoveQueueTracks" - RequestClearQueue = "RequestClearQueue" -) -``` - -### 2. `frontend/src/events.ts` — Add matching TypeScript event constant -Add `RequestClearQueue` to the queue events section. - -```typescript - RequestMoveQueueTracks: "RequestMoveQueueTracks", - RequestClearQueue: "RequestClearQueue", -``` - -### 3. `backend/queue/queue.go` — Wire event handler in `registerEventHandlers()` -Add a new `runtime.EventsOn` call at the end of `registerEventHandlers()` (after the existing `RequestMoveQueueTracks` handler around line 289): - -```go - runtime.EventsOn( - q.ctx, - events.RequestClearQueue, - func(_ ...any) { - q.logger.Info("Received RequestClearQueue") - q.Clear() - }, - ) -``` - -### 4. `frontend/src/store/queue-store.ts` — Add `clearQueue()` action -Add after the existing `moveTracksInQueue()` method (around line 250): - -```typescript - clearQueue(): void { - EventsEmit(Events.RequestClearQueue); - } -``` - -### 5. `frontend/src/components/queue-panel/queue-panel.ts` — Add UI button, styles, and handler - -#### 5a. Add handler method -Add a new handler method near the other handlers (around line 518, near `handleAddToPlaylist`): - -```typescript - private handleClearQueue = () => { - queueStore.clearQueue(); - }; -``` - -Note: Import `queueStore` — check if it's already imported (it likely is via the controller). - -#### 5b. Add CSS styles for shared header button class -Add a `.header-actions` container style and refactor the button styles. Replace the existing `.add-to-playlist-button` styles: - -**Replace:** -```css - .add-to-playlist-button { - background: none; - border: none; - color: inherit; - cursor: pointer; - padding: 4px; - display: flex; - align-items: center; - } - - .add-to-playlist-button:hover { - color: #ffd43b; - } - - .add-to-playlist-button:disabled { - color: #555; - cursor: not-allowed; - } -``` - -**With:** -```css - .header-actions { - display: flex; - align-items: center; - gap: 4px; - } - - .header-action-button { - background: none; - border: none; - color: inherit; - cursor: pointer; - padding: 4px; - display: flex; - align-items: center; - } - - .header-action-button:hover { - color: #ffd43b; - } - - .header-action-button:disabled { - color: #555; - cursor: not-allowed; - } -``` - -#### 5c. Update the header HTML -Replace the header section (around lines 1183-1193): - -**Replace:** -```html -

    -``` - -**Important:** The `add-to-playlist-button` class must remain on the playlist button because it's referenced by `@query` selectors and the `closePickerHandler` (lines 84-85, 527). The new class `header-action-button` provides the shared visual style. - -#### 5d. Update CSS selector references -Check that the `.add-to-playlist-button` query selector references still work. Since we're keeping `add-to-playlist-button` as a class on the playlist button, the existing `@query('.add-to-playlist-button')` and `querySelector('.add-to-playlist-button')` calls will continue to work unchanged. - -### 6.

Items are grouped by priority — tackle P1 before adding major new features, P2 as convenient, P3 opportunistically. + +--- + +## P1 — Should fix before adding major features + +### 1. Resolve `RequestPlay` dual-handler ambiguity + +**Problem:** Both `player.registerEventHandlers()` (`player.go`) and `queue.registerEventHandlers()` (`queue.go:182`) listen for the `RequestPlay` event. The player calls `Play()` (resume audio), while the queue calls `PlayFromStart()` (play from beginning if `currentIndex == -1`). Both fire on every `RequestPlay` event since Wails delivers to all listeners. + +**Why it matters:** This works by coincidence — `PlayFromStart` is a no-op when `currentIndex != -1`, so the two handlers don't conflict in the common case. But it's fragile and semantically confusing. A single event triggering two different actions in two packages is an anti-pattern that will cause bugs as the codebase grows. + +**Approach:** Remove the `RequestPlay` handler from the player. The queue should be the sole handler — it already calls `player.Play()` internally when needed. If the queue needs to distinguish "resume" from "play from start", add a separate event or an argument to the existing one. + +--- + +### 2. Remove player from Wails `FEBindings` (or remove event handlers) + +**Problem:** The player is added to `FEBindings` in `app.go:163`, which generates JS bindings for all exported methods (`Play()`, `Pause()`, `LoadFile()`, `Seek()`, `SetVolume()`, etc.). However, the frontend exclusively uses events for player control. This creates two parallel APIs for the same operations. + +**Why it matters:** It exposes internal lifecycle methods (`SetContext()`, `SaveState()`, `RestoreState()`) to the frontend as callable JS functions. New developers won't know which API to use. Any method added to the player automatically becomes a frontend-callable binding. + +**Approach:** Remove the player from `FEBindings`. The frontend uses events exclusively and the player doesn't need direct bindings. If `GetCurrentTrackInfo()` is needed as a binding for some edge case, extract it to a separate small struct that only exposes that method. + +--- + +### 3. Split `queue.go` (2254 lines) + +**Problem:** The queue package is a single 2254-line file containing types, state management, ~300 lines of event handler boilerplate, persistence logic, shuffle algorithms, and emit helpers. + +**Why it matters:** Hard to navigate, hard to review changes, easy to introduce bugs in unrelated sections. + +**Approach:** Split into focused files: +- `queue.go` — Core types (`Track`, `State`, `Queue` struct), constructor, `SetContext`, `SetPlayer` +- `handlers.go` — `registerEventHandlers()` and all `handle*` methods +- `persistence.go` — `persistTracks`, `persistState`, `RestoreState`, `SaveState`, `lookupTrackMetaBatch` +- `shuffle.go` — Shuffle order generation and navigation +- `emit.go` — All `emit*` methods + +--- + +### 4. Split `cover-grid.ts` (3740 lines) + +**Problem:** The largest frontend component by far. It likely handles album grid rendering, context menus, drag-and-drop, selection, sorting, resizing, and more — all in a single file. + +**Why it matters:** Difficult to understand, modify, or review. Changes to context menu logic risk breaking grid rendering and vice versa. + +**Approach:** Extract logical sections into separate files/components: +- Context menu logic into a shared utility or sub-component +- Selection logic already uses a `SelectionController` — verify it's fully extracted +- Drag-and-drop setup into the existing `DragController` if not already +- Grid rendering as the core component, delegating to these helpers + +--- + +## P2 — Fix when convenient + +### 5. Delete `backend/models/` package (dead code) + +**Problem:** The `models` package (`files.go`, `music.go`, `art.go`) defines `AudioFile`, `AudioFileType`, `Album`, `Track`, `Artist`, and `Art` types. No package imports it anywhere. + +**Why it matters:** Dead code creates confusion — new contributors may think these are the canonical domain types, but the actual types are in `library/`, `queue/`, `playlist/`, and `sqlcgen/`. + +**Approach:** Delete the entire `backend/models/` directory. + +--- + +### 6. Extract `SizedFilename` to a shared utility package + +**Problem:** `library.SizedFilename()` is a small string utility for generating thumbnail filenames. Both `player/player.go` and `playlist/playlist.go` import the entire `library` package solely for this function. + +**Why it matters:** Creates unnecessary coupling — `player` -> `library` and `playlist` -> `library` dependencies exist only for one utility function. + +**Approach:** Move `SizedFilename` to a shared package (e.g., `backend/coverart/` or `backend/fileutil/`). Update the three callers: `library/`, `player/`, and `playlist/`. + +--- + +### 7. Consolidate `LibraryScanComplete` handling + +**Problem:** `LibraryScanComplete` is listened to directly in 10+ components (`genres-view.ts`, `artists-view.ts`, `cover-grid.ts`, `track-list.ts`, `playlist-view.ts`, `genre-details.ts`, `artist-details.ts`, `playlist-picker.ts`, `config-page.ts`, `library-manager.ts`) in addition to `library-store.ts` and `playlist-store.ts`. Each component independently re-fetches its data. + +**Why it matters:** The stores already invalidate their caches and notify subscribers on this event. Components that use the store controllers should get re-rendered automatically. The direct listeners exist because many components load data independently from the stores (calling Go bindings directly), which means the stores aren't serving their full purpose as centralized data sources. + +**Approach:** For components that already use `LibraryController`/`PlaylistController`, the store subscription should handle cache invalidation. The controller's `hostConnected` subscribes and `requestUpdate` triggers a re-render, which calls the async data getter, which will re-fetch since the cache was invalidated. Remove the redundant direct `EventsOn(LibraryScanComplete)` from components that go through stores. For components like `playlist-picker.ts` that call Go bindings directly (bypassing stores), either route them through the store or accept the direct listener as intentional. + +--- + +### 8. Type the WebAwesome popup interactions (eliminate 49x `as any`) + +**Problem:** Every component with a context menu uses `(popup as any).anchor = ...` and `(popup as any).active = true`. This pattern appears 49 times across `track-list.ts`, `cover-grid.ts`, `queue-panel.ts`, `playlist-view.ts`, `genres-view.ts`, `artists-view.ts`. + +**Why it matters:** Type safety is completely bypassed for a core interaction pattern. Typos in property names (`actve` instead of `active`) would silently fail. + +**Approach:** Create a type declaration for the WebAwesome popup element (or find one in their package). Alternatively, write a small typed utility: +```typescript +function openPopup(popup: Element, anchor: Element | VirtualAnchor): void +function closePopup(popup: Element): void +``` +Replace all 49 `as any` casts with calls to these utilities. + +--- + +### 9. Replace `GetCurrentTrackInfo` `map[string]interface{}` with a struct + +**Problem:** `player.GetCurrentTrackInfo()` returns `map[string]interface{}` with stringly-typed keys (`"fileName"`, `"filePath"`, `"state"`, `"title"`, etc.). The `emitTrackChanged()` method mutates this map by adding keys after the fact. + +**Why it matters:** No compile-time safety — typos in key names are silent bugs. The Wails binding generator would produce typed TypeScript if given a struct. + +**Approach:** Define a `TrackInfo` struct in the player package with all the fields. Return it from `GetCurrentTrackInfo`. Update `emitTrackChanged` to build the struct directly instead of mutating a map. + +--- + +### 10. Move `FullRescan` orchestration from library to app + +**Problem:** `library.Library` holds references to the queue (`queueClearer` interface) and playlist service (`playlistRestorer` interface), set via `SetQueue()` and `SetPlaylistRestorer()`. The `FullRescan` method in `rescan.go` orchestrates clearing the queue and restoring playlists — cross-cutting concerns that aren't really library responsibilities. + +**Why it matters:** The library package shouldn't know about queue clearing or playlist restoration. This creates a dependency web (`app` -> `library` -> `queue`, `app` -> `library` -> `playlist`). + +**Approach:** Move the `FullRescan` orchestration to the `app` level. The app already has references to all three packages. The library would only expose `Scan()` and a `ClearAndRescan()` that handles only library concerns (clear DB, walk files, extract metadata). The app's `FullRescan` handler would call `queue.Clear()`, `library.ClearAndRescan()`, then `playlist.RestoreAll()`. + +--- + +### 11. Fix double `LibraryScanStarted` event during FullRescan + +**Problem:** `rescan.go:22` emits `LibraryScanStarted`, then calls `Scan()` which emits `LibraryScanStarted` again at `library.go:191`. The frontend receives two `LibraryScanStarted` events for a single full rescan. + +**Why it matters:** Frontend components may show duplicate "scanning" UI state transitions or start/reset loading indicators twice. + +**Approach:** Remove the `LibraryScanStarted` emission from either `FullRescan` or `Scan`. Since `Scan` is also called independently, keep it in `Scan` and remove it from `FullRescan`. + +--- + +### 12. Inconsistent communication patterns: queue (events) vs playlist (bindings) + +**Problem:** Queue operations use 14+ `Request*` events with manual `data[0].(type)` casting in ~300 lines of handler boilerplate. Playlist operations use direct Wails bindings with type-safe Go function signatures. + +**Why it matters:** Inconsistency makes the codebase harder to learn. The queue's event-only approach requires substantial boilerplate that the playlist avoids. New features on the queue require touching 4 files (Go event constant, TS event constant, Go handler, TS store method) vs 1-2 files for the playlist. + +**Approach:** This is a larger refactor. Two options: +1. **Move queue to bindings** (recommended): Add the queue to `FEBindings`, expose typed methods, call them directly from the frontend store. Remove the event handlers and the `Request*` events. Keep the backend-to-frontend events (`QueueChanged`, etc.) for state push. +2. **Accept the inconsistency**: Document the rationale (queue existed before playlists, events were the original pattern, bindings were adopted later). Add a comment in AGENTS.md. + +--- + +## P3 — Fix opportunistically + +### 13. Dead player methods: `ChangeVolume`, `MuteToggle`, `CurrentPosition` + +**Problem:** `ChangeVolume()` (`player.go`), `MuteToggle()` (`player.go`), and `CurrentPosition()` (percentage-based, `player.go`) have zero callers anywhere in the codebase. + +**Approach:** Delete them, or keep them if you plan to add keyboard shortcuts / media key support soon. + +--- + +### 14. Unused queue sentinels: `ErrEmptyQueue`, `ErrNoPlayer` + +**Problem:** Defined in `queue.go` but never returned or checked. + +**Approach:** Delete them, or wire them into the appropriate error paths if they were intended for future validation. + +--- + +### 15. `SeekFailed` event emitted but never listened to + +**Problem:** `player.go` emits `SeekFailed` when seeking fails, but no frontend code subscribes to it. Users get no feedback on seek failure. + +**Approach:** Either add a frontend listener that shows a brief notification/toast, or remove the event emission if seek failure feedback isn't needed. + +--- + +### 16. `path.Join` instead of `filepath.Join` in config + +**Problem:** `config/config.go:41` uses `path.Join` (POSIX paths) instead of `filepath.Join` (OS-aware paths) for constructing the config file path. + +**Approach:** Replace with `filepath.Join`. Single-line change. + +--- + +### 17. Replace 200ms sleep with frontend-ready handshake + +**Problem:** `app.go:205-216` uses `time.Sleep(200 * time.Millisecond)` before emitting state to the frontend, assuming it will be ready by then. + +**Approach:** Have the frontend emit a "ready" event when its stores have initialized. The backend listens for this event and then emits the current state. Eliminates the timing assumption. + +--- + +### 18. Custom `sortInts` in queue instead of `slices.Sort` + +**Problem:** `queue.go` has a hand-written insertion sort for int slices, but `slices.Sort()` is already used elsewhere in the same file. + +**Approach:** Replace the custom `sortInts` with `slices.Sort`. Single-line change. + +--- + +### 19. `playlist-picker.ts` bypasses `playlistStore` + +**Problem:** `playlist-picker.ts` calls `GetAllPlaylists()` directly from the Go binding instead of going through `playlistStore`. It fetches only summaries (not `WithTracks`), which is why it doesn't use the store. + +**Approach:** Either add a `getSummaries()` method to the playlist store that caches just the summary list, or accept this as intentional since the picker only needs summaries and the full `WithTracks` fetch would be wasteful for this use case. + +--- + +### 20. `library-manager.ts` and `config-page.ts` overlap + +**Problem:** Both components exist (different nav routes: "libraries" vs "settings"). `config-page.ts` has a comment saying scan metrics were "carried over from library-manager". They may have diverging copies of similar logic. + +**Approach:** Audit both components for duplicated logic. If the library manager's functionality is fully subsumed by the config page, consider removing it and redirecting the "libraries" nav route. diff --git a/backend/player/player.go b/backend/player/player.go index 5c3bb6d..b49cdb1 100644 --- a/backend/player/player.go +++ b/backend/player/player.go @@ -144,21 +144,6 @@ func (p *Player) registerEventHandlers() { return } - runtime.EventsOn( - ctx, - events.RequestPlay, - func(_ ...any) { - p.logger.Info("Received RequestPlayEvent") - - if err := p.Play(); err != nil { - p.logger.Warn( - "Play requested but not ready", - "err", err, - ) - } - }, - ) - runtime.EventsOn( ctx, events.RequestPause, diff --git a/backend/queue/queue.go b/backend/queue/queue.go index a8b1834..ac263a2 100644 --- a/backend/queue/queue.go +++ b/backend/queue/queue.go @@ -181,7 +181,7 @@ func (q *Queue) registerEventHandlers() { runtime.EventsOn(q.ctx, events.RequestPlay, func(_ ...any) { q.logger.Info("Received RequestPlay") - q.PlayFromStart() + q.Play() }) runtime.EventsOn(q.ctx, events.RequestNext, func(_ ...any) { @@ -1481,6 +1481,43 @@ func (q *Queue) Previous() { q.emitIndexChanged() } +// Play handles a play request by either resuming the current track or +// starting playback from the beginning of the queue.

Resolve `RequestPlay` dual-handler ambiguity - -**Problem:** Both `player.registerEventHandlers()` (`player.go`) and `queue.registerEventHandlers()` (`queue.go:182`) listen for the `RequestPlay` event. The player calls `Play()` (resume audio), while the queue calls `PlayFromStart()` (play from beginning if `currentIndex == -1`). Both fire on every `RequestPlay` event since Wails delivers to all listeners. - -**Why it matters:** This works by coincidence — `PlayFromStart` is a no-op when `currentIndex != -1`, so the two handlers don't conflict in the common case. But it's fragile and semantically confusing. A single event triggering two different actions in two packages is an anti-pattern that will cause bugs as the codebase grows. - -**Approach:** Remove the `RequestPlay` handler from the player. The queue should be the sole handler — it already calls `player.Play()` internally when needed.

However, the frontend exclusively uses events for player control. This creates two parallel APIs for the same operations. - -**Why it matters:** It exposes internal lifecycle methods (`SetContext()`, `SaveState()`, `RestoreState()`) to the frontend as callable JS functions. New developers won't know which API to use. Any method added to the player automatically becomes a frontend-callable binding. - -**Approach:** Remove the player from `FEBindings`. The frontend uses events exclusively and the player doesn't need direct bindings.

The `[]interface{} -> []int` conversion is in 2 handlers (`handleRemoveTracksFromQueue`, `handleMoveQueueTracks`). + +**New helpers:** +```go +// toStringSlice extracts strings from a Wails event argument. +func toStringSlice(raw []interface{}) []string { + result := make([]string, 0, len(raw)) + for _, v := range raw { + if s, ok := v.(string); ok { + result = append(result, s) + } + } + return result +} + +// toIntSlice extracts ints (from float64) from a Wails event argument. +func toIntSlice(raw []interface{}) []int { + result := make([]int, 0, len(raw)) + for _, v := range raw { + if f, ok := v.(float64); ok { + result = append(result, int(f)) + } + } + return result +} +``` + +Eliminates ~30 lines of repetition, centralizes type-coercion logic. + +### 3b. Extract `trackMeta.toTrack(position)` method (in `queue.go`) + +**Problem:** The `trackMeta` -> `Track` struct literal appears 7 times across `SetQueue`, `resolveRemainingTracks`, `AddTrack`, `AddTracks`, `InsertNextTracks`, `InsertNext`, `InsertTracksAt`. + +**New method:** +```go +// toTrack converts metadata lookup results into a queue Track. +func (m trackMeta) toTrack(position int64) Track { + return Track{ + AudioFileID: m.AudioFileID, + FilePath: m.FilePath, + Position: position, + Title: m.Title, + Artist: m.Artist, + } +} +``` + +Eliminates ~35 lines. Creates one authoritative mapping point — if a field is added to `Track`, only one place needs updating. + +### 3c. Extract `commitMutation(reindex bool)` helper (in `queue.go`) + +**Problem:** The post-mutation epilogue (reindex positions → regenerate shuffle order → persist tracks → persist state) is repeated in 8+ methods: `InsertNextTracks`, `InsertNext`, `InsertTracksAt`, `MoveQueueTracks`, `RemoveTrack`, `RemoveTracks`, `AddTracks`, `SetQueue` (small-batch path), `AddTrack` (after unification). + +**New helper:** +```go +// commitMutation persists the current queue state after a mutation. +// When reindex is true, track positions are renumbered first. +func (q *Queue) commitMutation(reindex bool) { + if reindex { + q.reindexPositions() + } + if q.shuffleMode { + q.generateShuffleOrder() + } + q.persistTracks() + q.persistState() +} +``` + +Eliminates ~40 lines. Ensures every mutation consistently applies the full epilogue — no risk of forgetting one of the steps. + +### 3d. Use `slices.Insert` for slice insertions (in `queue.go`) + +**Problem:** The manual tail-copy insertion pattern appears 3 times: +```go +tail := make([]Track, len(q.tracks[insertPos:])) +copy(tail, q.tracks[insertPos:]) +q.tracks = append(q.tracks[:insertPos], newTracks...) +q.tracks = append(q.tracks, tail...) +``` +in `InsertNextTracks`, `InsertTracksAt`, and `MoveQueueTracks`. `InsertNext` has a variant. + +**Fix:** Replace all with `q.tracks = slices.Insert(q.tracks, insertPos, newTracks...)`. The `slices` package is already imported. + +### 3e. Unify `AddTrack` persistence strategy (in `queue.go`) + +**Problem:** `AddTrack` is the only method that uses a single-row `InsertQueueTrack` DB call (line 834), while every other mutating method uses `persistTracks` (full table rewrite). This dual strategy means: +- If the single-row insert fails, the in-memory state diverges from the DB +- `AddTrack` has different error recovery behavior than all other methods +- The shuffle order append (line 847) is an optimization that `AddTracks` doesn't share, creating inconsistency + +**Fix:** Replace `AddTrack`'s custom DB insert with `commitMutation(false)` (no reindex needed since it appends). This makes it consistent with every other method. The performance cost of a full table rewrite for a single-track add is negligible for music-player queue sizes (typically <10K tracks). + +--- + +## Part 4: Cleanup (bundled from catalog #14 and #18) + +### 4a. Delete `sortInts`, use `slices.Sort` (catalog #18) + +**Location:** `queue.go:1274-1281` (current) + +Delete the hand-rolled insertion sort. Replace its one call site in `MoveQueueTracks` (`sortInts(sorted)` → `slices.Sort(sorted)`). `slices.Sort` is already used elsewhere in the same file (line 1364). + +### 4b. Remove exported `PlayFromStart` wrapper + +**Location:** `queue.go:1521-1530` (current) + +`PlayFromStart` is exported but has zero callers outside the package. The unexported `playFromStart` already exists. Remove the exported wrapper — if external access is ever needed, it can be re-added. + +--- + +## Execution Order + +The order matters because later steps depend on earlier ones: + +1. **Replace `sortInts` with `slices.Sort`** — single-line change, eliminates a function before the split +2. **Remove `PlayFromStart`** — eliminates dead code before the split +3. **Add `trackMeta.toTrack()` method** — replace all 7 call sites +4. **Add `commitMutation()` helper** — replace all 8+ call sites +5. **Fix `InsertNext` empty-queue bug** — add `wasEmpty` guard +6. **Fix `AddTracks` persist ordering** — move index assignment before persist +7. **Unify `AddTrack` persistence** — replace custom insert with `commitMutation` +8. **Use `slices.Insert`** — replace 3-4 manual insertion patterns +9. **Extract `handlers.go`** — move `OnPlaybackFinished`, `registerEventHandlers`, all `handle*` methods; add `toStringSlice`/`toIntSlice` helpers; update all 6 call sites +10. **Extract `emit.go`** — move all 4 `emit*` methods +11. **Extract `navigation.go`** — move all 6 navigation/shuffle functions +12. **Extract `persistence.go`** — move all 7 persistence/lookup functions +13. **Clean up `queue.go` imports** — remove now-unused imports (`encoding/json`, `fmt`, `strings`, `math/rand/v2`, `errors`, `yellowjacket/backend/events`, `yellowjacket/backend/database/sql/sqlcgen`) +14. **Delete `ErrEmptyQueue` and `ErrNoPlayer`** — unused sentinels (catalog #14) +15. **Run `make lint`** — fix any formatting/import-order issues +16. **Run `make test`** — verify nothing is broken (note: no queue-specific tests exist, but this catches compilation errors and any tests that depend on queue indirectly) +17. **Update refactoring catalog** — mark #3, #14, #18 as solved + +## Risk Assessment + +**Very low risk.** All files remain in the same `queue` package — field access, unexported methods, and mutex sharing work identically across files within a package. The Go compiler catches any missing imports or broken references at build time. The two bug fixes change behavior only in edge cases that are currently broken. The DRY extractions are mechanical transformations that preserve identical behavior. + +## What This Does NOT Change + +- No changes to the public API surface (except removing unused `PlayFromStart` and the unused sentinels) +- No changes to the mutex strategy or locking granularity +- No changes to the event system or frontend +- No changes to database schema or query logic +- No new

The queue's event-only approach requires substantial boilerplate that the playlist avoids. New features on the queue require touching 4 files (Go event constant, TS event constant, Go handler, TS store method) vs 1-2 files for the playlist. **Approach:** This is a larger refactor. Two options: + 1. **Move queue to bindings** (recommended): Add the queue to `FEBindings`, expose typed methods, call them directly from the frontend store. Remove the event handlers and the `Request*` events. Keep the backend-to-frontend events (`QueueChanged`, etc.) for state push. 2. **Accept the inconsistency**: Document the rationale (queue existed before playlists, events were the original pattern, bindings were adopted later).

The same context menu pattern is duplicated in 6 components. + +**Extract the common pattern from all 6 components:** + +```typescript +import type { ReactiveController, ReactiveControllerHost } from 'lit'; + +export interface ContextMenuHost extends ReactiveControllerHost { + // Query accessors — each component provides its own popup element refs + getContextMenuPopup(): HTMLElement | undefined; + getPlaylistSubmenuPopup(): HTMLElement | undefined; + updateComplete: Promise; + shadowRoot: ShadowRoot | null; +} + +export class ContextMenuController implements ReactiveController { + // Reactive state (component reads these for rendering) + contextMenuOpen = false; + playlistSubmenuOpen = false; + playlistFilePaths: string[] = []; + + constructor(host: ContextMenuHost); + + // Lifecycle — registers/removes document-level listeners + hostConnected(): void; + hostDisconnected(): void; + + // Actions + openAt(clientX: number, clientY: number): void; + close(): void; + showPlaylistSubmenu(filePaths: string[]): Promise; + closePlaylistSubmenu(): void; + onPlaylistActionComplete(): void; +} +``` + +**Also extract** shared context menu CSS styles as: +```typescript +export const contextMenuStyles = css` + #context-menu { ... } + .context-menu-panel { ... } + wa-dropdown-item { ... } + .submenu-item { ... } + .submenu-arrow { ... } + #playlist-submenu { ... } +`; +``` + +**What stays in each component:** +- The `renderContextMenu()` method — menu items differ per component (cover-grid has conditional "Track Details", queue-panel has "Remove" instead of "Add to Queue", etc.) +- The `onContextMenuAction(action)` handler — file path resolution differs per component +- The `@query` decorators for popup elements (passed to controller via host interface) + +**Components to update (6):** +1. `cover-grid.ts` — Remove ~200 lines of inline context menu code +2. `track-list.ts` — Remove ~200 lines +3. `playlist-view.ts` — Remove ~200 lines (keep the second playlist-level context menu as-is or also migrate) +4. `queue-panel.ts` — Remove ~200 lines +5. `genres-view.ts` — Remove ~200 lines +6. `artists-view.ts` — Remove ~200 lines + +**Bonus:** All 49× `(popup as any).anchor = ...` and `(popup as any).active = ...` casts are now centralized in one file. This partially addresses catalog item #8 — adding proper typing to the controller's internals eliminates the `as any` from all 6 components. + +**Rationale:** ReactiveController is the right shape here (unlike ScrollManager) because it manages document-level event listeners tied to the component lifecycle via `hostConnected`/`hostDisconnected`. This matches the existing `SelectionController` pattern in `utils/`. + +--- + +## Part 5: Album Selection Manager → `album-selection.ts` + +**New file:** `frontend/src/components/cover-grid/album-selection.ts` (~250 lines) + +**Move from `cover-grid.ts`:** +- Album selection: `selectAlbumRange()` (line 2378), `getSelectedAlbumFilePaths()` (line 2398), `getContextMenuAlbumFilePaths()` (line 2422), `getAlbumFilePaths()` (line 2449) +- Drag cache: `warmAlbumFilePathCache()` (line 2471), `getCachedSelectedAlbumFilePaths()` (line 2505), `albumFilePathCache` Map +- Track selection: `selectTrackRange()` (line 2528), `getSelectedTrackFilePaths()` (line 2547) +- Dropdown coupling: `closeDropdown()` (line 2561), `openDropdown()` (line 2575), `syncDropdownToSelection()` (line 2607) + +**Shape:** +```typescript +export class AlbumSelectionManager { + selectedAlbums = new Set(); + selectedTracks = new Set(); + expandedAlbumId: number | null = null; + expandedTracks: library.Track[] = []; + lastSelectedAlbumIndex: number | null = null; + lastSelectedTrackIndex: number | null = null; + + private albumFilePathCache = new Map(); + + // Album selection + selectAlbumRange(from: number, to: number, filteredAlbums: library.Album[]): Set; + async getSelectedAlbumFilePaths(albums: library.Album[]): Promise; + async getContextMenuAlbumFilePaths(contextMenuAlbumId: number | null, albums: library.Album[]): Promise; + + // Drag cache + async warmCache(albums: library.Album[]): Promise; + getCachedSelectedPaths(albums: library.Album[]): string[]; + + // Track selection + selectTrackRange(from: number, to: number): Set; + getSelectedTrackFilePaths(): string[]; + + // Dropdown + async openDropdown(album: library.Album): Promise; + closeDropdown(): void; + syncDropdownToSelection(filteredAlbums: library.Album[]): void; + + // Reset + clear(): void; +} +``` + +**Why not use the existing `SelectionController`?** The existing controller: +- Uses string keys only; album selection uses numeric IDs +- Manages a single selection set; cover-grid has separate album and track selections +- Has no concept of dropdown coupling (selecting 1 album → opens dropdown) +- Has no file path caching for drag + +Retrofitting `SelectionController` to handle all of this would make it overly complex for its other consumers (`track-list.ts`, `playlist-view.ts`, `queue-panel.ts`). A dedicated manager for cover-grid's dual album/track model is cleaner. + +**Rationale:** Selection state + file path resolution is a coherent concern (~250 lines) that doesn't need access to the DOM, making it easy to extract. The main component's event handlers become thin wrappers that call into this manager. + +--- + +## What Stays in `cover-grid.ts` + +After all extractions and improvements, the main file will be approximately **~1700 lines** (down from 3774): + +| Section | ~Lines | Why it stays | +|---------|--------|-------------| +| Imports and class declaration | 60 | Structural | +| Properties, state, queries, controllers | 100 | Component-specific reactive state (fewer `@state` props) | +| Grid layout creation + memoization | 80 | Tightly coupled to virtualizer | +| Lifecycle (connectedCallback, disconnectedCallback, willUpdate, updated) | 350 | Orchestration — wires managers together (debug logs removed) | +| Dynamic size properties + zoom | 70 | Simple, component-specific | +| Data loading | 30 | Simple async fetch | +| Virtualizer item builders | 40 | Depends on component state (memoized) | +| Event handlers (album + track + drag) | 340 | Thin delegation to managers | +| Render methods | 430 | Templates reference component state | +| Sort toolbar logic | 120 | Small, self-contained | + +~1700 lines is still substantial, but the *complexity* is dramatically reduced because the three hardest subsystems (scroll management, context menus, selection/file-path resolution) are encapsulated in dedicated modules. The remaining code is pure orchestration and rendering. + +--- + +## What This Does NOT Do + +- **Does not split into multiple custom elements** — Artificial component boundaries would add event-forwarding complexity for no UX benefit. +- **Does not refactor the split/single virtualizer architecture** — That's the core rendering strategy; changing it is a separate effort. +- **Does not retrofit `SelectionController` for albums** — The existing controller serves different consumers with simpler needs. See Part 5 rationale. +- **Does not touch `album-dropdown.ts`** — Already a well-scoped 410-line sub-component. +- **Does not extract drag handlers** — ~165 lines of glue code that delegates to existing `drag-controller.ts`/`drag-image.ts`. Diminishing returns. + +--- + +## Part 6: Code Quality and Performance Improvements + +These improvements are applied during the extraction steps that touch the relevant code. They don't change behavior — they make the same behavior more efficient and clean. + +### 6a. Remove 13 `console.log` debug statements + +**Lines:** 1133, 1151, 1192, 1226, 1303, 1320, 1328, 1390, 1432, 1437, 2158, 2176, 2345 + +The scroll restoration and transition overlay code contains 13 `console.log` calls that are clearly development debugging artifacts (e.g., `[willUpdate] exit split (tracks empty)`, `[updated] scroll restore start`, `[adjustScroll]`, `[restoreScrollTop] attempt ${i}`). + +**Action:** Remove all 13 `console.log` calls. Keep the 3 `console.error` (actual failures) and 1 `console.warn` (retry exhaustion). + +**Applied during:** Part 3 (scroll-manager extraction) and Part 5 lifecycle cleanup. + +### 6b. Memoize `buildGridEntries()` — eliminates 3-5 redundant array allocations per render + +**Problem:** `buildGridEntries()` allocates a new `GridEntry[]` array on every call. In split-mode rendering, it's called up to 5 times per render cycle: +- `getBeforeEntries()` → `buildGridEntries().slice(0, splitIndex)` (line 2003) +- `getAfterEntries()` called **twice** in `renderSplitGrid()` — once for `.length > 0` check (line 3612), once for `.items` (line 3616) — each rebuilding the full array +- `onVisibilityChanged` scroll handler also rebuilds it (line 1637) + +There's even a placeholder comment on line 340: `// buildGridEntries() memoization cache.` — but no cache was ever implemented. + +**Action:** +1. Cache the `GridEntry[]` result, keyed on `cachedFilteredAlbums` reference identity. Invalidate in `recomputeAlbumCache()`. +2. In `renderSplitGrid()`, compute `const afterEntries = this.getAfterEntries()` once and reuse for both the length check and the `.items` binding. + +**Applied during:** Part 1 (types — `GridEntry` moves) and main file cleanup. + +### 6c. Cache expanded album index — eliminates 6 redundant O(n) scans + +**Problem:** `cachedFilteredAlbums.findIndex((a) => a.ID === this.expandedAlbumId)` appears at 6 call sites (lines 1077, 1364, 1813, 1919, 1959, 2276). Each is a linear scan of the album array for the same ID. + +**Action:** Compute `expandedAlbumIndex` in `recomputeAlbumCache()` (or in `willUpdate` when `expandedAlbumId` changes). All 6 call sites become a direct property read. Invalidate when either `expandedAlbumId` or `cachedFilteredAlbums` changes. + +**Applied during:** Part 3 (scroll-manager extraction — 4 of the 6 sites are in scroll code) and main file cleanup. + +### 6d. Build `albumById` Map for O(1) selection lookups + +**Problem:** `getSelectedAlbumFilePaths()` (line 2401) and `warmAlbumFilePathCache()` (line 2472) both call `this.albums.filter(a => selectedAlbums.has(a.ID))` to find selected albums — an O(n) scan of the full album list. `resolveTrackCoverArt()` (line 3181) does `this.albums.find(a => a.Name === albumName)` — an O(n) name-based scan that could also match the wrong album if names collide. + +**Action:** Build a `Map` (keyed by album ID) when `albums` changes. Selection lookups iterate `selectedAlbums` and do O(1) map lookups. `resolveTrackCoverArt()` uses the map with `expandedAlbumId` instead of name-based search. + +**Applied during:** Part 5 (album-selection extraction). + +### 6e. Remove unnecessary `@state()` from 2 properties + +**Problem:** 15 properties have `@state()`. Two don't need it: +- `playlistFilePaths` (line 695) — only rendered inside the playlist submenu, which is conditionally shown when `playlistSubmenuOpen` is true. Since `showPlaylistSubmenu()` sets `playlistFilePaths` before setting `playlistSubmenuOpen`, the reactive update from `playlistSubmenuOpen` will render with the correct paths. `playlistFilePaths` itself doesn't need to trigger a re-render. +- `splitIndex` (line 737) — only used to compute `getBeforeEntries()`/`getAfterEntries()`. It's always set before `splitMode` changes (which triggers the render), so it doesn't need independent reactivity. + +**Action:** Remove `@state()` decorator from both. Make them plain private fields. + +**Applied during:** Main file cleanup after extractions. + +### 6f. Single-pass `onGridClick` path traversal + +**Problem:** `onGridClick` (line 3071) calls `composedPath()` once, then iterates it twice with `.some()` — once for `.album-card` and once for `.album-dropdown`. + +**Action:** Single loop checking both classes: +```typescript +for (const el of e.composedPath()) { + if (!(el instanceof HTMLElement)) continue; + if (el.classList.contains('album-card') || + el.classList.contains('album-dropdown')) return; +} +``` + +**Applied during:** Main file cleanup. + +### 6g. Use expanded album directly for cover art resolution + +**Problem:** `resolveTrackCoverArt(albumName)` (line 3176) does an O(n) `.find()` on `this.albums` by `Name` to get cover art URLs. But we already know which album is expanded (`expandedAlbumId`), and all tracks in the dropdown belong to that album. Name-based lookup has a theoretical collision risk if two albums share the same name. + +**Action:** Replace the name-based search with a direct lookup using `expandedAlbumId` and the `albumById` map from improvement 6d. Falls back gracefully if the album isn't found. + +**Applied during:** Part 5 (album-selection extraction) or main file cleanup. + +### 6h. Prune `albumFilePathCache` to prevent unbounded growth + +**Problem:** The `albumFilePathCache` (Map) is warmed when albums are selected and read during dragstart, but entries are never removed. Over a session, it grows without bound. + +**Action:** +1. Clear the entire cache when `albums` changes (library rescan). +2. After `warmAlbumFilePathCache()` completes, remove entries whose album ID is no longer in `selectedAlbums`. + +**Applied during:** Part 5 (album-selection extraction — the cache moves to `AlbumSelectionManager`). + +--- + +## Execution Order + +| Step | File(s) | Risk | Notes | +|------|---------|------|-------| +| 1 | `cover-grid-types.ts` | Minimal | Pure move, no logic changes | +| 2 | `cover-grid-styles.ts` | Minimal | Pure move, verify `static styles` array works | +| 3 | `utils/context-menu-controller.ts` | Medium | Widest blast radius — update 6 components | +| 4 | `album-selection.ts` + improvements 6d, 6g, 6h | Low | Contained to cover-grid | +| 5 | `scroll-manager.ts` + improvements 6a, 6c | Medium | Largest extraction, deep state interaction | +| 6 | Main file cleanup: improvements 6b, 6e, 6f | Low | After extractions, clean up remaining code | +| 7 | Verify: `pnpm build` + `pnpm exec tsc --noEmit` | — | Ensure no type errors or build failures | + +Steps 1-2 are safe warmups.

Eliminates redundant direct `LibraryScanComplete` event listeners from components by making stores eagerly re-fetch data after invalidation, so the existing reactive controller subscription (`requestUpdate()`) delivers fresh data automatically. + +--- + +## Problem Analysis + +The refactoring catalog describes 10+ components that each independently listen for `LibraryScanComplete` and re-fetch their data. It claims these listeners are redundant because "the stores already invalidate their caches and notify subscribers." + +**This claim is incorrect in the current architecture.** Here is why: + +1. When `LibraryScanComplete` fires, `LibraryStore.invalidate()` nulls out cached data (`tracks`, `albums`, `artists`) and calls `notify()`. +2. `notify()` triggers subscriber callbacks, which are `LibraryController.host.requestUpdate()` — a Lit re-render. +3. But `requestUpdate()` only re-runs `render()`, and components read from **local `@state()` properties** (e.g., `this.tracks`, `this.albums`), not from the store. The local data is still stale. +4. Nobody calls the `loadTracks()`/`loadAlbums()` methods again except the direct `LibraryScanComplete` listener. + +**The root cause:** the stores use **lazy-fetch** — `invalidate()` clears the cache but does not re-fetch. The next `getTracks()` call will hit the backend, but nothing triggers that call except the component's own event listener. + +**The fix:** make stores **eagerly re-fetch** after invalidation, so when the controller calls `requestUpdate()`, the store already has fresh data. Then refactor components to read data reactively from the store/controller instead of from local state populated by imperative load calls. + +--- + +## Guiding Principles + +1. **Incremental migration.** The store change (eager refetch) is backwards-compatible. Components are migrated one by one from easiest to hardest. Both patterns (old imperative + new reactive) coexist during migration. + +2. **Preserve existing UX.** Scroll restoration, selection clearing, loading indicators, and search filtering must work identically. No regressions. + +3. **Three categories of listeners.** Not all `LibraryScanComplete` listeners are the same: + - **Data refresh listeners** (8 components): re-fetch library/playlist data → these are what we're consolidating. + - **UI status listeners** (`config-page`, `library-manager`): update scan progress UI and display metrics → these MUST keep their direct listeners since no store handles scan status. + - **Store-bypassing listeners** (`playlist-picker`): calls Go bindings directly → addressed separately. + +4. **Don't fight the `externalAlbums`/`externalTracks` pattern.** Parent-child data delegation (`artist-details` → `cover-grid`, `genre-details` → `track-list`) is a valid pattern. The parent gets migrated; the child already skips the scan listener when driven externally. + +--- + +## Phase 0: Store Eager-Refetch + +### 0A. `LibraryStore` — add eager refetch after invalidation + +**File:** `frontend/src/store/library-store.ts` + +Change `invalidate()` to eagerly re-fetch all three data types after clearing the cache. The existing `getTracks()`/`getAlbums()`/`getArtists()` methods already handle concurrent-request coalescing (via `waitFor*()` helpers) and notify subscribers when loading starts/finishes. + +```typescript +// Before: +private invalidate(): void { + this.tracks = null; + this.albums = null; + this.artists = null; + this.scrollPositions = { tracks: 0, albums: 0, artists: 0, genres: 0 }; + this.notify(); +} + +// After: +private invalidate(): void { + this.tracks = null; + this.albums = null; + this.artists = null; + this.scrollPositions = { tracks: 0, albums: 0, artists: 0, genres: 0 }; + this.notify(); + this.eagerRefetch(); +} + +private eagerRefetch(): void { + // Fire-and-forget. Each getter handles its own error/loading state + // and calls notify() when done, which triggers requestUpdate() + // on all subscribed controllers. + void this.getTracks(); + void this.getAlbums(); + void this.getArtists(); +} +``` + +**Why this works:** After `eagerRefetch()`, the store is in a `loading=true` state. When the backend responses arrive, the cache is repopulated and `notify()` fires again (from the `finally` block in each getter). Controllers call `requestUpdate()`, and now any component reading from the store gets fresh data. + +**Why it's backwards-compatible:** Components with direct listeners will still call their `load*()` methods. The store's `waitFor*()` helpers coalesce concurrent requests, so the eager fetch and the component's fetch share the same in-flight promise — no duplicate backend calls. + +**Scroll position reset note:** The `scrollPositions` reset to `0` happens synchronously in `invalidate()`. This is correct — after a library scan, the content has changed and scroll positions are meaningless. Components that read scroll positions during their re-render will see `0`. + +### 0B. `PlaylistStore` — add eager refetch after invalidation + +**File:** `frontend/src/store/playlist-store.ts` + +Same pattern. The `invalidate()` method already exists and is called from multiple event handlers (not just `LibraryScanComplete`). + +```typescript +// Before: +invalidate(): void { + this.playlists = null; + this.scrollPosition = 0; + this.notify(); +} + +// After: +invalidate(): void { + this.playlists = null; + this.scrollPosition = 0; + this.notify(); + void this.getPlaylists(); +} +``` + +**Note:** `PlaylistStore.invalidate()` is public (called by `PlaylistController.invalidate()`). This eager refetch will also run for `PlaylistCreated`, `PlaylistDeleted`, `PlaylistRenamed`, `PlaylistTracksChanged`, and `PlaylistsRestored` events — which is desirable. Currently those events invalidate the cache and wait for a component to lazily re-fetch. Eager refetch means subscribers see fresh data faster. + +### 0C. Verification + +After Phase 0, both stores eagerly re-fetch on invalidation. Components with existing direct listeners still work (their fetches coalesce with the eager fetch). Components without listeners now get fresh data automatically through the controller subscription path, though they still need to read it reactively (Phase 1+). + +--- + +## Phase 1: Migrate `genre-details` and `artist-details` (LOW effort) + +These are thin wrapper components that fetch data, filter/cache it, and pass it to a child via `externalTracks`/`externalAlbums`. The child already skips its own scan listener when receiving external data. + +### 1A. `genre-details.ts` + +**File:** `frontend/src/components/genre-details/genre-details.ts` + +Current flow: +1. `connectedCallback()` → `loadTracks()` → `libraryCtrl.getTracks()` → filter by genre → `this.tracks = filtered` +2. `LibraryScanComplete` → `loadTracks()` again + +New flow: +1. `connectedCallback()` → `loadTracks()` (initial load, unchanged) +2. Remove the direct `LibraryScanComplete` listener and its cancellation +3. Add reactive consumption in `willUpdate()` or `updated()`: when the store notifies (cache repopulated after eager refetch), the controller calls `requestUpdate()`, triggering a re-render. In `willUpdate()`, detect that the store's cached tracks have changed (or that loading finished) and re-run the genre filtering. + +Implementation approach — use `updated()` to react to controller-triggered re-renders: + +```typescript +// Remove from connectedCallback: +// this.cancelScanComplete = EventsOn(Events.LibraryScanComplete, () => this.loadTracks()); +// Remove from disconnectedCallback: +// this.cancelScanComplete?.(); +// Remove the cancelScanComplete field. + +// Add a version counter to detect store changes: +private lastStoreVersion = 0; + +override updated() { + // The library controller's subscription calls requestUpdate() when the + // store notifies. Check if tracks have been refreshed since our last load. + const storeVersion = this.libraryCtrl.storeVersion; + if (storeVersion !== this.lastStoreVersion && !this.libraryCtrl.tracksLoading) { + this.lastStoreVersion = storeVersion; + this.loadTracks(); + } +} +``` + +**Alternative (simpler):** Instead of a version counter, check if the store's cached tracks reference has changed. Since `invalidate()` sets tracks to `null` and the eager refetch populates a new array, we can compare object identity: + +```typescript +private lastTracksRef: library.Track[] | null = null; + +override updated() { + const cached = this.libraryCtrl.cachedTracks; + if (cached !== null && cached !== this.lastTracksRef) { + this.lastTracksRef = cached; + this.loadTracks(); + } +} +``` + +**Decision: Use the reference-comparison approach.** It's simpler, doesn't require adding version counters to the store, and leverages the fact that each eager refetch creates a new array instance. + +However, there's a subtlety: `updated()` runs after every render, including renders triggered by the component's own `@state()` changes (like `this.tracks` being set). We need to ensure this doesn't create an infinite loop: +- `loadTracks()` calls `libraryCtrl.getTracks()`, which if the cache is already populated returns the same reference. +- `this.tracks` is set to the filtered result, triggering a render. +- `updated()` runs, compares `cachedTracks` — same reference as `lastTracksRef`, so no re-load. Safe. + +But the initial load path: `connectedCallback()` calls `loadTracks()` directly. At that point `cachedTracks` might be `null` (store hasn't loaded yet). After `loadTracks()` finishes, the store cache is populated, and `lastTracksRef` is set. Next `requestUpdate()` from the store won't trigger a re-load because the reference matches. Safe. + +**Required controller addition:** Add a `storeVersion` or expose `cachedTracks` — the controller already exposes `cachedTracks` (line 72-74 of `library-controller.ts`). No changes needed to the controller. + +### 1B. `artist-details.ts` + +**File:** `frontend/src/components/artist-details/artist-details.ts` + +Same approach. This component has a cache-then-fetch dual-load pattern (`getAlbumsByArtistNameCached` then `getAlbumsByArtist`). The scan-complete handler just calls `loadAlbums()`. + +Changes: +1. Remove the direct `LibraryScanComplete` listener and its cancellation. +2. Add reference comparison in `updated()`: + +```typescript +private lastAlbumsRef: library.Album[] | null = null; + +override updated() { + const cached = this.libraryCtrl.cachedAlbums; + if (cached !== null && cached !== this.lastAlbumsRef) { + this.lastAlbumsRef = cached; + this.loadAlbums(); + } +} +``` + +**Note:** `getAlbumsByArtist(artistId)` is NOT cached by the store — it always hits the backend. But that's fine because `loadAlbums()` already handles this. The reference check on `cachedAlbums` (the full album list) serves as a proxy for "the library data has changed." + +--- + +## Phase 2: Migrate `artists-view` (LOW-MEDIUM effort) + +**File:** `frontend/src/components/artists-view/artists-view.ts` + +Current flow: +1. `connectedCallback()` → `loadArtists()` → `libraryCtrl.getArtists()` → `this.artists = result` +2. `LibraryScanComplete` → `loadArtists()` +3. `willUpdate()` → `recomputeArtistCaches()` (filters by search term) +4. `render()` reads `cachedGridEntries` + +New flow: +1. `connectedCallback()` → `loadArtists()` (initial load, unchanged) +2. Remove the direct `LibraryScanComplete` listener. +3. React to store changes in `updated()`: + +```typescript +private lastArtistsRef: library.Artist[] | null = null; + +override updated() { + const cached = this.libraryCtrl.cachedArtists; + if (cached !== null && cached !== this.lastArtistsRef) { + this.lastArtistsRef = cached; + this.loadArtists(); + } +} +``` + +**Scroll position consideration:** `loadArtists()` currently restores scroll position at the end. After a scan, scroll positions are reset to `0` by `invalidate()`. The `restoringScroll` flag and `restoreScrollPosition()` call in `loadArtists()` handle this correctly — they'll restore to position `0`, which is a no-op visually. + +**Selection consideration:** `loadArtists()` does not currently clear selection. After migration, selection could reference stale artist IDs. Consider adding `this.selectedArtists.clear()` at the top of `loadArtists()` if not already present. (This is a minor improvement, not a regression from the migration.) + +--- + +## Phase 3: Migrate `genres-view` (HIGH effort) + +**File:** `frontend/src/components/genres-view/genres-view.ts` + +This component derives genres from tracks — a transformation the store doesn't provide. The store exposes tracks, not genres. + +Current flow: +1. `loadGenres()` → `libraryCtrl.getTracks()` → `extractGenres(tracks)` → `this.genres = result` +2. `LibraryScanComplete` → `loadGenres()` + +New flow: +1. Same `loadGenres()` for initial load. +2. Remove the direct `LibraryScanComplete` listener. +3. React to store changes in `updated()` using `cachedTracks` reference comparison: + +```typescript +private lastTracksRef: library.Track[] | null = null; + +override updated() { + // Existing updated() logic for search term, size properties, etc. + // stays unchanged. Add this at the end: + const cached = this.libraryCtrl.cachedTracks; + if (cached !== null && cached !== this.lastTracksRef) { + this.lastTracksRef = cached; + this.loadGenres(); + } +} +``` + +**Why not move genre extraction to the store?** The store's job is to cache backend data, not derive view-specific aggregations. Genres are only needed by `genres-view` and `genre-details`. Adding genre derivation to the store would couple it to a specific UI concern. The component is the right place for this derivation. + +**Scroll/selection considerations:** Same as `artists-view`. `loadGenres()` handles scroll restoration. Consider adding `this.selectedGenres.clear()` if not already present. + +--- + +## Phase 4: Migrate `track-list` (MEDIUM effort) + +**File:** `frontend/src/components/track-list/track-list.ts` + +This has a dual-source pattern (`externalTracks` vs store fetch). The scan listener is already conditionally registered: + +```typescript +if (this.externalTracks) { + this.tracks = this.externalTracks; +} else { + this.loadTracks(); + this.cancelScanComplete = EventsOn(Events.LibraryScanComplete, () => this.loadTracks()); +} +``` + +New flow: +1. Keep the `externalTracks` path unchanged — when a parent provides tracks, the parent is responsible for refreshing (and the parent's migration in Phase 1/3 handles this). +2. For the standalone path (no `externalTracks`): + - `connectedCallback()` → `loadTracks()` (initial load, unchanged) + - Remove the `LibraryScanComplete` listener registration + - Add reactive consumption in `updated()`, guarded by `!this.externalTracks`: + +```typescript +private lastTracksRef: library.Track[] | null = null; + +override updated() { + // ... existing updated() logic ... + + if (!this.externalTracks) { + const cached = this.libraryCtrl.cachedTracks; + if (cached !== null && cached !== this.lastTracksRef) { + this.lastTracksRef = cached; + this.loadTracks(); + } + } +} +``` + +**Selection consideration:** `loadTracks()` already clears selection. Safe. + +--- + +## Phase 5: Migrate `playlist-view` (HIGH effort) + +**File:** `frontend/src/components/playlist-view/playlist-view.ts` + +This component reshapes `playlist.WithTracks[]` into `PlaylistEntry[]` with an `expanded` boolean per entry. It has a `refreshPlaylists()` method that preserves expanded state across refetches. + +Current flow: +1. `loadPlaylists()` → `playlistCtrl.getPlaylists()` → map to `PlaylistEntry[]` → `this.entries = result` +2. `LibraryScanComplete` → `loadPlaylists()` + +New flow: +1. `connectedCallback()` → `loadPlaylists()` (initial load, unchanged) +2. Remove the direct `LibraryScanComplete` listener. +3. React to store changes in `updated()`: + +```typescript +private lastPlaylistsRef: playlist.WithTracks[] | null = null; + +override updated() { + // ... existing updated() logic ... + + const cached = this.playlistCtrl.cachedPlaylists; + if (cached !== null && cached !== this.lastPlaylistsRef) { + this.lastPlaylistsRef = cached; + this.refreshPlaylists(); // preserves expanded state + } +} +``` + +**Key choice: use `refreshPlaylists()` instead of `loadPlaylists()`.** The `refreshPlaylists()` method preserves which playlists are expanded, providing a better UX after a scan completes. `loadPlaylists()` resets all to collapsed. The current scan-complete handler uses `loadPlaylists()` (collapsing everything), but since we're improving the architecture anyway, switching to `refreshPlaylists()` is a UX improvement. + +**Alternative consideration:** If `loadPlaylists()` is preferred (to reset UI state after a scan), that works too. The choice is a UX decision, not a technical constraint. + +--- + +## Phase 6: Migrate `cover-grid` (VERY HIGH effort) + +**File:** `frontend/src/components/cover-grid/cover-grid.ts` + +The most complex component. Dual-source pattern, split-mode scroll management, sort/filter pipeline. + +Current flow: +1. `loadAlbums()` → `libraryCtrl.getAlbums()` or `externalAlbums` → `this.albums = result` +2. Only registers scan listener when `!this.externalAlbums` +3. `LibraryScanComplete` → `loadAlbums()` + +New flow: +1. Keep the `externalAlbums` path unchanged. +2. For the standalone path: + - `connectedCallback()` → `loadAlbums()` (initial load, unchanged) + - Remove the `LibraryScanComplete` listener registration + - Add reactive consumption in `updated()`, guarded by `!this.externalAlbums`: + +```typescript +private lastAlbumsRef: library.Album[] | null = null; + +override updated() { + // ... existing updated() logic (size properties, wheel listener, + // grid layout, search term selection clearing) ... + + if (!this.externalAlbums) { + const cached = this.libraryCtrl.cachedAlbums; + if (cached !== null && cached !== this.lastAlbumsRef) { + this.lastAlbumsRef = cached; + this.loadAlbums(); + } + } +} +``` + +**Split-mode consideration:** If the album dropdown is open (`expandedAlbumId !== null`) when a scan completes, `loadAlbums()` will close it (resets `expandedAlbumId` and `expandedTracks`). This is the same behavior as the current direct listener. The split-mode transition logic in `willUpdate()` will handle the layout change. + +**Selection consideration:** `loadAlbums()` already clears album selection. Safe. + +--- + +## Phase 7: Cleanup and Documentation + +### 7A. Remove unused imports + +After all data-refresh components are migrated, remove unused `EventsOn` and `Events` imports from migrated components (only if no other events are listened to in that component). + +### 7B. Components that KEEP their direct listeners + +These components are explicitly excluded from migration and should be documented: + +| Component | Reason | +|---|---| +| `config-page.ts` | Uses event for UI status (scan progress, metrics display), not data refresh.

The reference comparison catches both "new data arrived" and "data was cleared and refetched." +- **No infinite loops:** Setting `this.lastDataRef = cached` before calling `loadData()` prevents re-triggering. The `loadData()` call may set local `@state()` which triggers another `updated()`, but by then `lastDataRef` matches `cached` and the guard short-circuits. +- **No store changes needed:** The controllers already expose `cachedTracks`, `cachedAlbums`, `cachedArtists`, `cachedPlaylists`. + +**Why not move everything into `render()`:** Components do significant local work beyond just displaying store data — filtering, sorting, scroll restoration, selection management. Keeping the imperative `loadData()` call but triggering it reactively is the minimal change that achieves the goal. + +--- + +## Risk Assessment + +| Risk | Mitigation | +|---|---| +| Double fetch on scan complete (eager + component listener during migration) | Store's `waitFor*()` helpers coalesce concurrent requests. Only one backend call actually fires. | +| Infinite `updated()` loop | Reference comparison with `lastDataRef` assignment prevents re-triggering. Each migration should be tested for this. | +| Stale selection after scan | `loadData()` methods already clear selection in most components. Verify for each migration. | +| Scroll position regression | `invalidate()` resets scroll to `0`. `loadData()` methods handle scroll restoration. The `0` position means "start from top", which is correct after a scan. | +| `externalAlbums`/`externalTracks` components don't refresh | Parent components (`artist-details`, `genre-details`) are migrated first. They re-fetch and update the `external*` property, which triggers the child's `willUpdate()` change detection. | +| `playlist-picker` left unmigrated | Intentional. It uses a different API (`GetAllPlaylists` vs `GetAllPlaylistsWithTracks`).

A question arises: should `getCurrentTrackInfoLocked` return a "partial" struct (10 fields) while `emitTrackChanged` extends it with 3 more? No — the whole point is to eliminate the mutation pattern. A single struct with all 13 fields is cleaner. The struct represents "everything the frontend needs to know about the current track for the TrackChanged event." + +**Reasoning:** A single struct means one source of truth for the shape of the data. The zero values for `TrackLength`, `SeekPosition`, and `TrackChangeID` are naturally `0` in Go, which is semantically correct for "no track loaded" or "error" fallback cases. + +### Decision 2: Use `json` struct tags with camelCase keys + +The existing map uses camelCase keys (`"fileName"`, `"coverArtSmall"`, etc.). Wails serializes event payloads as JSON. The struct must use `json:"fileName"` tags to preserve the exact same wire format — otherwise the frontend would break. + +**Reasoning:** This is a behavioral requirement, not a style choice. The frontend `TrackInfo` interface expects camelCase keys. Changing them would require coordinated frontend changes for zero benefit. + +### Decision 3: Keep `getCurrentTrackInfoLocked` but change its return type + +Rather than inlining all logic into `emitTrackChanged`, keep the `getCurrentTrackInfoLocked` helper but have it return `TrackInfo` (with the base 10 fields populated). Then `emitTrackChanged` fills in the remaining 3 fields (`TrackLength`, `SeekPosition`, `TrackChangeID`) on the struct before emitting. + +**Reasoning:** This preserves the separation of concerns — "build metadata from file/DB" vs "compute playback position and emit." It also keeps `GetCurrentTrackInfo()` (the public method) useful: it returns the same struct, just without the playback-timing fields (which are zero-valued). If the player is ever added to `FEBindings`, this method's return type would auto-generate a TypeScript class. + +### Decision 4: Eliminate `GetCurrentTrackInfo()` public method — or keep it? + +`GetCurrentTrackInfo()` has **zero Go callers** and **zero TypeScript callers** (the player is not in `FEBindings`). It exists only as dead code. However, it was likely intended as a Wails binding that hasn't been wired up yet, and it could be useful in the future. + +**Decision: Keep it.** The cost of a single unused method is minimal, and it now returns a proper struct which would be useful if the player is added to `FEBindings` later. If desired, it can be removed as part of a separate cleanup (item #13 addresses dead player methods). + +### Decision 5: Fix the inconsistent nil-file/error fallbacks + +Currently: +- **nil file fallback** (line 840-848): returns 7 keys — missing `coverArtSmall`, `coverArtMedium`, `coverArtLarge` +- **error fallback** in `emitTrackChanged` (line 319-323): returns only 3 keys — missing most fields + +With a struct, both fallbacks naturally return a fully-populated struct (all fields present, most set to zero values). The `State` field should still be set explicitly in both cases. This eliminates the inconsistency for free. + +### Decision 6: Place the struct in the existing `player.go` file, not a new file + +The player package has only 3 files (`player.go`, `volume.go`, `player_test.go`). The struct is tightly coupled to the player — it describes what the player emits. Creating a separate `trackinfo.go` file for a single ~20-line struct definition would be premature file splitting for such a small package. + +**Reasoning:** Follow the existing pattern — `State` type and playback constants are already defined in `player.go`. The `TrackInfo` struct logically belongs alongside them. + +### Decision 7: Use `State` type (not `string`) in the struct + +Currently the map stores `string(p.state)` — explicitly converting the `State` type to `string`. The struct should use the `State` type with `json:"state"` tag. Since `State` is `type State string`, JSON serialization produces the same string value. This gives us type safety in Go without changing the wire format. + +**Reasoning:** The whole point of this refactoring is compile-time safety. Using `string` in the struct for the state field would undermine that goal. + +### Decision 8: Use `uint64` for `TrackChangeID` (match the field type) + +The `Player` struct defines `trackChangeID uint64`. The struct field should be `TrackChangeID uint64`. The frontend `TrackInfo` interface uses `number` which can safely represent integers up to 2^53 — more than sufficient for a monotonic counter that starts at 0 per session. + +--- + +## Implementation Plan + +### Step 1: Define the `TrackInfo` struct in `player.go` + +Add the struct definition near the existing `State` type (around line 58-65), after the sentinel errors: + +```go +// TrackInfo contains metadata and playback state for the currently loaded track. +type TrackInfo struct { + FileName string `json:"fileName"` + FilePath string `json:"filePath"` + State State `json:"state"` + Title string `json:"title"` + Artist string `json:"artist"` + Album string `json:"album"` + CoverArt string `json:"coverArt"` + CoverArtSmall string `json:"coverArtSmall"` + CoverArtMedium string `json:"coverArtMedium"` + CoverArtLarge string `json:"coverArtLarge"` + TrackLength int `json:"trackLength"` + SeekPosition int `json:"seekPosition"` + TrackChangeID uint64 `json:"trackChangeId"` +} +``` + +**Note:** `json:"trackChangeId"` (lowercase `d`) matches the existing frontend interface key `trackChangeId`. + +### Step 2: Refactor `getCurrentTrackInfoLocked` to return `TrackInfo` + +Change the signature from `(map[string]interface{}, error)` to `TrackInfo` (no error needed — see reasoning below). + +**Why remove the error return?** The current function never actually returns an error. It handles all error cases internally (DB lookup failure logs and falls back to defaults). The error in the return signature is unused dead weight. With a struct, the zero-value fallback is even cleaner. + +Updated implementation: + +```go +func (p *Player) getCurrentTrackInfoLocked() TrackInfo { + info := TrackInfo{ + State: p.state, + } + + if p.currentFile == nil { + return info + } + + info.FileName = filepath.Base(p.currentFile.Name()) + info.FilePath = p.currentFile.Name() + info.Title = info.FileName // default title + + if p.db != nil { + meta, err := p.db.Queries.GetTrackMetadataByPath( + p.ctx, info.FilePath, + ) + if err == nil { + if meta.Title != "" { + info.Title = meta.Title + } + + info.Artist = meta.Artist + info.Album = meta.Album + + if meta.CoverArtPath != "" { + base := filepath.Base(meta.CoverArtPath) + info.CoverArt = "/covers/" + base + info.CoverArtSmall = "/covers/" + + library.SizedFilename(base, "_sm") + info.CoverArtMedium = "/covers/" + + library.SizedFilename(base, "_md") + info.CoverArtLarge = "/covers/" + + library.SizedFilename(base, "_lg") + } + } else { + p.logger.Debug( + "Could not get track metadata from database", + "path", info.FilePath, "err", err, + ) + } + } + + return info +} +``` + +### Step 3: Update `GetCurrentTrackInfo` (public method) + +Change return type from `(map[string]interface{}, error)` to `TrackInfo`: + +```go +// GetCurrentTrackInfo returns information about the currently loaded track. +func (p *Player) GetCurrentTrackInfo() TrackInfo { + p.mu.Lock() + defer p.mu.Unlock() + + return p.getCurrentTrackInfoLocked() +} +``` + +**Note:** Dropping the error return is safe — there are zero callers of this method. + +### Step 4: Refactor `emitTrackChanged` to build the struct directly + +Replace map mutation with direct struct field assignment: + +```go +func (p *Player) emitTrackChanged() { + if p.ctx == nil { + p.logger.Error("Context is nil, cannot emit event") + + return + } + + trackInfo := p.getCurrentTrackInfoLocked() + + trackLengthSecs, err := p.trackLengthLocked() + if err != nil { + p.logger.Error("Cannot get track length") + } + + trackInfo.TrackLength = trackLengthSecs + + // Compute current seek position in seconds. + if p.seeker != nil { + speaker.Lock() + trackInfo.SeekPosition = p.seeker.Position() / + int(p.format.SampleRate) + speaker.Unlock() + } + + // Increment track change ID so the frontend can detect changes + // even when the same file plays consecutively. + p.trackChangeID++ + trackInfo.TrackChangeID = p.trackChangeID + + runtime.EventsEmit(p.ctx, events.TrackChanged, trackInfo) + + p.logger.Info( + "Emitting TrackChangedEvent with track info", + "trackInfo", trackInfo, + ) +} +``` + +**Key change:** No more error-fallback map with only 3 keys. If `getCurrentTrackInfoLocked()` returns a zero-valued struct (e.g., when no file is loaded), it still has all 13 fields — the frontend receives a complete, predictable shape every time. + +### Step 5: Verify `UnloadTrack` emits `nil` (no change needed) + +At `player.go:678`, `UnloadTrack` emits: +```go +runtime.EventsEmit(p.ctx, events.TrackChanged, nil) +``` + +This is correct and intentional — it signals "no track loaded" to the frontend, which handles `null` in `(trackInfo: TrackInfo | null) => { ... }`. No changes needed here. + +### Step 6: Run `make lint` and `make test` + +Ensure: +- No linting violations (line length, godot, nlreturn, etc.) +- Tests pass (the existing test is integration-only and skips in CI, but the build itself must succeed with `-tags webkit2_41`) + +### Step 7: (Optional) Update the frontend `TrackInfo` interface comments + +The frontend `TrackInfo` interface in `frontend/src/store/player-store.ts` already matches the struct fields exactly. No field changes are needed. However, a comment noting that it mirrors `player.TrackInfo` from the backend could be helpful for future maintainers: + +```typescript +// TrackInfo mirrors the player.TrackInfo struct in the Go backend. +// Fields are serialized as camelCase JSON via struct tags. +export interface TrackInfo { + // ... (existing fields, unchanged) +} +``` + +--- + +## Files Changed + +| File | Change | +|------|--------| +| `backend/player/player.go` | Add `TrackInfo` struct; refactor `getCurrentTrackInfoLocked`, `GetCurrentTrackInfo`, and `emitTrackChanged` | +| `frontend/src/store/player-store.ts` | Add comment noting Go struct mirror (optional) | + +**No other files need changes.** The frontend receives the data via events and the JSON wire format is identical (same keys, same types).

Eliminates redundant direct `LibraryScanComplete` event listeners from components by making stores eagerly re-fetch data after invalidation, so the existing reactive controller subscription (`requestUpdate()`) delivers fresh data automatically. - ---- - -## Problem Analysis - -The refactoring catalog describes 10+ components that each independently listen for `LibraryScanComplete` and re-fetch their data. It claims these listeners are redundant because "the stores already invalidate their caches and notify subscribers." - -**This claim is incorrect in the current architecture.** Here is why: - -1. When `LibraryScanComplete` fires, `LibraryStore.invalidate()` nulls out cached data (`tracks`, `albums`, `artists`) and calls `notify()`. -2. `notify()` triggers subscriber callbacks, which are `LibraryController.host.requestUpdate()` — a Lit re-render. -3. But `requestUpdate()` only re-runs `render()`, and components read from **local `@state()` properties** (e.g., `this.tracks`, `this.albums`), not from the store. The local data is still stale. -4. Nobody calls the `loadTracks()`/`loadAlbums()` methods again except the direct `LibraryScanComplete` listener. - -**The root cause:** the stores use **lazy-fetch** — `invalidate()` clears the cache but does not re-fetch. The next `getTracks()` call will hit the backend, but nothing triggers that call except the component's own event listener. - -**The fix:** make stores **eagerly re-fetch** after invalidation, so when the controller calls `requestUpdate()`, the store already has fresh data. Then refactor components to read data reactively from the store/controller instead of from local state populated by imperative load calls. - ---- - -## Guiding Principles - -1. **Incremental migration.** The store change (eager refetch) is backwards-compatible. Components are migrated one by one from easiest to hardest. Both patterns (old imperative + new reactive) coexist during migration. - -2. **Preserve existing UX.** Scroll restoration, selection clearing, loading indicators, and search filtering must work identically. No regressions. - -3. **Three categories of listeners.** Not all `LibraryScanComplete` listeners are the same: - - **Data refresh listeners** (8 components): re-fetch library/playlist data → these are what we're consolidating. - - **UI status listeners** (`config-page`, `library-manager`): update scan progress UI and display metrics → these MUST keep their direct listeners since no store handles scan status. - - **Store-bypassing listeners** (`playlist-picker`): calls Go bindings directly → addressed separately. - -4. **Don't fight the `externalAlbums`/`externalTracks` pattern.** Parent-child data delegation (`artist-details` → `cover-grid`, `genre-details` → `track-list`) is a valid pattern. The parent gets migrated; the child already skips the scan listener when driven externally. - ---- - -## Phase 0: Store Eager-Refetch - -### 0A. `LibraryStore` — add eager refetch after invalidation - -**File:** `frontend/src/store/library-store.ts` - -Change `invalidate()` to eagerly re-fetch all three data types after clearing the cache. The existing `getTracks()`/`getAlbums()`/`getArtists()` methods already handle concurrent-request coalescing (via `waitFor*()` helpers) and notify subscribers when loading starts/finishes. - -```typescript -// Before: -private invalidate(): void { - this.tracks = null; - this.albums = null; - this.artists = null; - this.scrollPositions = { tracks: 0, albums: 0, artists: 0, genres: 0 }; - this.notify(); -} - -// After: -private invalidate(): void { - this.tracks = null; - this.albums = null; - this.artists = null; - this.scrollPositions = { tracks: 0, albums: 0, artists: 0, genres: 0 }; - this.notify(); - this.eagerRefetch(); -} - -private eagerRefetch(): void { - // Fire-and-forget. Each getter handles its own error/loading state - // and calls notify() when done, which triggers requestUpdate() - // on all subscribed controllers. - void this.getTracks(); - void this.getAlbums(); - void this.getArtists(); -} -``` - -**Why this works:** After `eagerRefetch()`, the store is in a `loading=true` state. When the backend responses arrive, the cache is repopulated and `notify()` fires again (from the `finally` block in each getter). Controllers call `requestUpdate()`, and now any component reading from the store gets fresh data. - -**Why it's backwards-compatible:** Components with direct listeners will still call their `load*()` methods. The store's `waitFor*()` helpers coalesce concurrent requests, so the eager fetch and the component's fetch share the same in-flight promise — no duplicate backend calls. - -**Scroll position reset note:** The `scrollPositions` reset to `0` happens synchronously in `invalidate()`. This is correct — after a library scan, the content has changed and scroll positions are meaningless. Components that read scroll positions during their re-render will see `0`. - -### 0B. `PlaylistStore` — add eager refetch after invalidation - -**File:** `frontend/src/store/playlist-store.ts` - -Same pattern. The `invalidate()` method already exists and is called from multiple event handlers (not just `LibraryScanComplete`). - -```typescript -// Before: -invalidate(): void { - this.playlists = null; - this.scrollPosition = 0; - this.notify(); -} - -// After: -invalidate(): void { - this.playlists = null; - this.scrollPosition = 0; - this.notify(); - void this.getPlaylists(); -} -``` - -**Note:** `PlaylistStore.invalidate()` is public (called by `PlaylistController.invalidate()`). This eager refetch will also run for `PlaylistCreated`, `PlaylistDeleted`, `PlaylistRenamed`, `PlaylistTracksChanged`, and `PlaylistsRestored` events — which is desirable. Currently those events invalidate the cache and wait for a component to lazily re-fetch. Eager refetch means subscribers see fresh data faster. - -### 0C. Verification - -After Phase 0, both stores eagerly re-fetch on invalidation. Components with existing direct listeners still work (their fetches coalesce with the eager fetch). Components without listeners now get fresh data automatically through the controller subscription path, though they still need to read it reactively (Phase 1+). - ---- - -## Phase 1: Migrate `genre-details` and `artist-details` (LOW effort) - -These are thin wrapper components that fetch data, filter/cache it, and pass it to a child via `externalTracks`/`externalAlbums`. The child already skips its own scan listener when receiving external data. - -### 1A. `genre-details.ts` - -**File:** `frontend/src/components/genre-details/genre-details.ts` - -Current flow: -1. `connectedCallback()` → `loadTracks()` → `libraryCtrl.getTracks()` → filter by genre → `this.tracks = filtered` -2. `LibraryScanComplete` → `loadTracks()` again - -New flow: -1. `connectedCallback()` → `loadTracks()` (initial load, unchanged) -2. Remove the direct `LibraryScanComplete` listener and its cancellation -3. Add reactive consumption in `willUpdate()` or `updated()`: when the store notifies (cache repopulated after eager refetch), the controller calls `requestUpdate()`, triggering a re-render. In `willUpdate()`, detect that the store's cached tracks have changed (or that loading finished) and re-run the genre filtering. - -Implementation approach — use `updated()` to react to controller-triggered re-renders: - -```typescript -// Remove from connectedCallback: -// this.cancelScanComplete = EventsOn(Events.LibraryScanComplete, () => this.loadTracks()); -// Remove from disconnectedCallback: -// this.cancelScanComplete?.(); -// Remove the cancelScanComplete field. - -// Add a version counter to detect store changes: -private lastStoreVersion = 0; - -override updated() { - // The library controller's subscription calls requestUpdate() when the - // store notifies. Check if tracks have been refreshed since our last load. - const storeVersion = this.libraryCtrl.storeVersion; - if (storeVersion !== this.lastStoreVersion && !this.libraryCtrl.tracksLoading) { - this.lastStoreVersion = storeVersion; - this.loadTracks(); - } -} -``` - -**Alternative (simpler):** Instead of a version counter, check if the store's cached tracks reference has changed. Since `invalidate()` sets tracks to `null` and the eager refetch populates a new array, we can compare object identity: - -```typescript -private lastTracksRef: library.Track[] | null = null; - -override updated() { - const cached = this.libraryCtrl.cachedTracks; - if (cached !== null && cached !== this.lastTracksRef) { - this.lastTracksRef = cached; - this.loadTracks(); - } -} -``` - -**Decision: Use the reference-comparison approach.** It's simpler, doesn't require adding version counters to the store, and leverages the fact that each eager refetch creates a new array instance. - -However, there's a subtlety: `updated()` runs after every render, including renders triggered by the component's own `@state()` changes (like `this.tracks` being set). We need to ensure this doesn't create an infinite loop: -- `loadTracks()` calls `libraryCtrl.getTracks()`, which if the cache is already populated returns the same reference. -- `this.tracks` is set to the filtered result, triggering a render. -- `updated()` runs, compares `cachedTracks` — same reference as `lastTracksRef`, so no re-load. Safe. - -But the initial load path: `connectedCallback()` calls `loadTracks()` directly. At that point `cachedTracks` might be `null` (store hasn't loaded yet). After `loadTracks()` finishes, the store cache is populated, and `lastTracksRef` is set. Next `requestUpdate()` from the store won't trigger a re-load because the reference matches. Safe. - -**Required controller addition:** Add a `storeVersion` or expose `cachedTracks` — the controller already exposes `cachedTracks` (line 72-74 of `library-controller.ts`). No changes needed to the controller. - -### 1B. `artist-details.ts` - -**File:** `frontend/src/components/artist-details/artist-details.ts` - -Same approach. This component has a cache-then-fetch dual-load pattern (`getAlbumsByArtistNameCached` then `getAlbumsByArtist`). The scan-complete handler just calls `loadAlbums()`. - -Changes: -1. Remove the direct `LibraryScanComplete` listener and its cancellation. -2. Add reference comparison in `updated()`: - -```typescript -private lastAlbumsRef: library.Album[] | null = null; - -override updated() { - const cached = this.libraryCtrl.cachedAlbums; - if (cached !== null && cached !== this.lastAlbumsRef) { - this.lastAlbumsRef = cached; - this.loadAlbums(); - } -} -``` - -**Note:** `getAlbumsByArtist(artistId)` is NOT cached by the store — it always hits the backend. But that's fine because `loadAlbums()` already handles this. The reference check on `cachedAlbums` (the full album list) serves as a proxy for "the library data has changed." - ---- - -## Phase 2: Migrate `artists-view` (LOW-MEDIUM effort) - -**File:** `frontend/src/components/artists-view/artists-view.ts` - -Current flow: -1. `connectedCallback()` → `loadArtists()` → `libraryCtrl.getArtists()` → `this.artists = result` -2. `LibraryScanComplete` → `loadArtists()` -3. `willUpdate()` → `recomputeArtistCaches()` (filters by search term) -4. `render()` reads `cachedGridEntries` - -New flow: -1. `connectedCallback()` → `loadArtists()` (initial load, unchanged) -2. Remove the direct `LibraryScanComplete` listener. -3. React to store changes in `updated()`: - -```typescript -private lastArtistsRef: library.Artist[] | null = null; - -override updated() { - const cached = this.libraryCtrl.cachedArtists; - if (cached !== null && cached !== this.lastArtistsRef) { - this.lastArtistsRef = cached; - this.loadArtists(); - } -} -``` - -**Scroll position consideration:** `loadArtists()` currently restores scroll position at the end. After a scan, scroll positions are reset to `0` by `invalidate()`. The `restoringScroll` flag and `restoreScrollPosition()` call in `loadArtists()` handle this correctly — they'll restore to position `0`, which is a no-op visually. - -**Selection consideration:** `loadArtists()` does not currently clear selection. After migration, selection could reference stale artist IDs. Consider adding `this.selectedArtists.clear()` at the top of `loadArtists()` if not already present. (This is a minor improvement, not a regression from the migration.) - ---- - -## Phase 3: Migrate `genres-view` (HIGH effort) - -**File:** `frontend/src/components/genres-view/genres-view.ts` - -This component derives genres from tracks — a transformation the store doesn't provide. The store exposes tracks, not genres. - -Current flow: -1. `loadGenres()` → `libraryCtrl.getTracks()` → `extractGenres(tracks)` → `this.genres = result` -2. `LibraryScanComplete` → `loadGenres()` - -New flow: -1. Same `loadGenres()` for initial load. -2. Remove the direct `LibraryScanComplete` listener. -3. React to store changes in `updated()` using `cachedTracks` reference comparison: - -```typescript -private lastTracksRef: library.Track[] | null = null; - -override updated() { - // Existing updated() logic for search term, size properties, etc. - // stays unchanged. Add this at the end: - const cached = this.libraryCtrl.cachedTracks; - if (cached !== null && cached !== this.lastTracksRef) { - this.lastTracksRef = cached; - this.loadGenres(); - } -} -``` - -**Why not move genre extraction to the store?** The store's job is to cache backend data, not derive view-specific aggregations. Genres are only needed by `genres-view` and `genre-details`. Adding genre derivation to the store would couple it to a specific UI concern. The component is the right place for this derivation. - -**Scroll/selection considerations:** Same as `artists-view`. `loadGenres()` handles scroll restoration. Consider adding `this.selectedGenres.clear()` if not already present. - ---- - -## Phase 4: Migrate `track-list` (MEDIUM effort) - -**File:** `frontend/src/components/track-list/track-list.ts` - -This has a dual-source pattern (`externalTracks` vs store fetch). The scan listener is already conditionally registered: - -```typescript -if (this.externalTracks) { - this.tracks = this.externalTracks; -} else { - this.loadTracks(); - this.cancelScanComplete = EventsOn(Events.LibraryScanComplete, () => this.loadTracks()); -} -``` - -New flow: -1. Keep the `externalTracks` path unchanged — when a parent provides tracks, the parent is responsible for refreshing (and the parent's migration in Phase 1/3 handles this). -2. For the standalone path (no `externalTracks`): - - `connectedCallback()` → `loadTracks()` (initial load, unchanged) - - Remove the `LibraryScanComplete` listener registration - - Add reactive consumption in `updated()`, guarded by `!this.externalTracks`: - -```typescript -private lastTracksRef: library.Track[] | null = null; - -override updated() { - // ... existing updated() logic ... - - if (!this.externalTracks) { - const cached = this.libraryCtrl.cachedTracks; - if (cached !== null && cached !== this.lastTracksRef) { - this.lastTracksRef = cached; - this.loadTracks(); - } - } -} -``` - -**Selection consideration:** `loadTracks()` already clears selection. Safe. - ---- - -## Phase 5: Migrate `playlist-view` (HIGH effort) - -**File:** `frontend/src/components/playlist-view/playlist-view.ts` - -This component reshapes `playlist.WithTracks[]` into `PlaylistEntry[]` with an `expanded` boolean per entry. It has a `refreshPlaylists()` method that preserves expanded state across refetches. - -Current flow: -1. `loadPlaylists()` → `playlistCtrl.getPlaylists()` → map to `PlaylistEntry[]` → `this.entries = result` -2. `LibraryScanComplete` → `loadPlaylists()` - -New flow: -1. `connectedCallback()` → `loadPlaylists()` (initial load, unchanged) -2. Remove the direct `LibraryScanComplete` listener. -3. React to store changes in `updated()`: - -```typescript -private lastPlaylistsRef: playlist.WithTracks[] | null = null; - -override updated() { - // ... existing updated() logic ... - - const cached = this.playlistCtrl.cachedPlaylists; - if (cached !== null && cached !== this.lastPlaylistsRef) { - this.lastPlaylistsRef = cached; - this.refreshPlaylists(); // preserves expanded state - } -} -``` - -**Key choice: use `refreshPlaylists()` instead of `loadPlaylists()`.** The `refreshPlaylists()` method preserves which playlists are expanded, providing a better UX after a scan completes. `loadPlaylists()` resets all to collapsed. The current scan-complete handler uses `loadPlaylists()` (collapsing everything), but since we're improving the architecture anyway, switching to `refreshPlaylists()` is a UX improvement. - -**Alternative consideration:** If `loadPlaylists()` is preferred (to reset UI state after a scan), that works too. The choice is a UX decision, not a technical constraint. - ---- - -## Phase 6: Migrate `cover-grid` (VERY HIGH effort) - -**File:** `frontend/src/components/cover-grid/cover-grid.ts` - -The most complex component. Dual-source pattern, split-mode scroll management, sort/filter pipeline. - -Current flow: -1. `loadAlbums()` → `libraryCtrl.getAlbums()` or `externalAlbums` → `this.albums = result` -2. Only registers scan listener when `!this.externalAlbums` -3. `LibraryScanComplete` → `loadAlbums()` - -New flow: -1. Keep the `externalAlbums` path unchanged. -2. For the standalone path: - - `connectedCallback()` → `loadAlbums()` (initial load, unchanged) - - Remove the `LibraryScanComplete` listener registration - - Add reactive consumption in `updated()`, guarded by `!this.externalAlbums`: - -```typescript -private lastAlbumsRef: library.Album[] | null = null; - -override updated() { - // ... existing updated() logic (size properties, wheel listener, - // grid layout, search term selection clearing) ... - - if (!this.externalAlbums) { - const cached = this.libraryCtrl.cachedAlbums; - if (cached !== null && cached !== this.lastAlbumsRef) { - this.lastAlbumsRef = cached; - this.loadAlbums(); - } - } -} -``` - -**Split-mode consideration:** If the album dropdown is open (`expandedAlbumId !== null`) when a scan completes, `loadAlbums()` will close it (resets `expandedAlbumId` and `expandedTracks`). This is the same behavior as the current direct listener. The split-mode transition logic in `willUpdate()` will handle the layout change. - -**Selection consideration:** `loadAlbums()` already clears album selection. Safe. - ---- - -## Phase 7: Cleanup and Documentation - -### 7A. Remove unused imports - -After all data-refresh components are migrated, remove unused `EventsOn` and `Events` imports from migrated components (only if no other events are listened to in that component). - -### 7B. Components that KEEP their direct listeners - -These components are explicitly excluded from migration and should be documented: - -| Component | Reason | -|---|---| -| `config-page.ts` | Uses event for UI status (scan progress, metrics display), not data refresh.

The ordering above goes from easiest to hardest as a recommended sequence. - ---- - -## Reactive Pattern: Reference Comparison - -All component migrations use the same pattern to detect store data changes: - -```typescript -private lastDataRef: T[] | null = null; - -override updated() { - const cached = this.controller.cachedData; - if (cached !== null && cached !== this.lastDataRef) { - this.lastDataRef = cached; - this.loadData(); // existing imperative load method - } -} -``` - -**Why reference comparison instead of a version counter or dirty flag:** -- **Simplicity:** No store API changes needed. `cachedTracks`/`cachedAlbums`/`cachedArtists`/`cachedPlaylists` are already exposed by controllers. -- **Correctness:** Each backend fetch creates a new array instance. `invalidate()` sets cache to `null`. The reference comparison catches both "new data arrived" and "data was cleared and refetched." -- **No infinite loops:** Setting `this.lastDataRef = cached` before calling `loadData()` prevents re-triggering. The `loadData()` call may set local `@state()` which triggers another `updated()`, but by then `lastDataRef` matches `cached` and the guard short-circuits. -- **No store changes needed:** The controllers already expose `cachedTracks`, `cachedAlbums`, `cachedArtists`, `cachedPlaylists`. - -**Why not move everything into `render()`:** Components do significant local work beyond just displaying store data — filtering, sorting, scroll restoration, selection management. Keeping the imperative `loadData()` call but triggering it reactively is the minimal change that achieves the goal. - ---- - -## Risk Assessment - -| Risk | Mitigation | -|---|---| -| Double fetch on scan complete (eager + component listener during migration) | Store's `waitFor*()` helpers coalesce concurrent requests. Only one backend call actually fires. | -| Infinite `updated()` loop | Reference comparison with `lastDataRef` assignment prevents re-triggering. Each migration should be tested for this. | -| Stale selection after scan | `loadData()` methods already clear selection in most components. Verify for each migration. | -| Scroll position regression | `invalidate()` resets scroll to `0`. `loadData()` methods handle scroll restoration. The `0` position means "start from top", which is correct after a scan. | -| `externalAlbums`/`externalTracks` components don't refresh | Parent components (`artist-details`, `genre-details`) are migrated first. They re-fetch and update the `external*` property, which triggers the child's `willUpdate()` change detection. | -| `playlist-picker` left unmigrated | Intentional. It uses a different API (`GetAllPlaylists` vs `GetAllPlaylistsWithTracks`). See catalog item #19. | - ---- - -## Testing Strategy - -For each phase: -1. **Manual test:** Trigger a library scan while each affected view is visible. Verify data refreshes without stale content. -2. **Manual test:** Trigger a scan while a detail view is open (`genre-details`, `artist-details`). Verify child components (`track-list`, `cover-grid`) refresh via the parent's external data update. -3. **Manual test:** Verify scroll position resets to top after scan. -4. **Manual test:** Verify that adding/removing tracks from the library directory and scanning updates all views correctly. -5. **Verify no console errors** — especially no infinite loop warnings or unhandled promise rejections. -6. **Run `pnpm exec tsc --noEmit`** — ensure no TypeScript errors after each phase. diff --git a/.opencode/plans/refactoring-catalog.md b/.opencode/plans/refactoring-catalog.md index 7c63ee6..aa6e6f0 100644 --- a/.opencode/plans/refactoring-catalog.md +++ b/.opencode/plans/refactoring-catalog.md @@ -42,30 +42,11 @@ Prioritized list of architectural improvements identified during a full codebase --- -### 8.

A dedicated manager for cover-grid's dual album/track model is cleaner. - -**Rationale:** Selection state + file path resolution is a coherent concern (~250 lines) that doesn't need access to the DOM, making it easy to extract. The main component's event handlers become thin wrappers that call into this manager. - ---- - -## What Stays in `cover-grid.ts` - -After all extractions and improvements, the main file will be approximately **~1700 lines** (down from 3774): - -| Section | ~Lines | Why it stays | -|---------|--------|-------------| -| Imports and class declaration | 60 | Structural | -| Properties, state, queries, controllers | 100 | Component-specific reactive state (fewer `@state` props) | -| Grid layout creation + memoization | 80 | Tightly coupled to virtualizer | -| Lifecycle (connectedCallback, disconnectedCallback, willUpdate, updated) | 350 | Orchestration — wires managers together (debug logs removed) | -| Dynamic size properties + zoom | 70 | Simple, component-specific | -| Data loading | 30 | Simple async fetch | -| Virtualizer item builders | 40 | Depends on component state (memoized) | -| Event handlers (album + track + drag) | 340 | Thin delegation to managers | -| Render methods | 430 | Templates reference component state | -| Sort toolbar logic | 120 | Small, self-contained | - -~1700 lines is still substantial, but the *complexity* is dramatically reduced because the three hardest subsystems (scroll management, context menus, selection/file-path resolution) are encapsulated in dedicated modules. The remaining code is pure orchestration and rendering. - ---- - -## What This Does NOT Do - -- **Does not split into multiple custom elements** — Artificial component boundaries would add event-forwarding complexity for no UX benefit. -- **Does not refactor the split/single virtualizer architecture** — That's the core rendering strategy; changing it is a separate effort. -- **Does not retrofit `SelectionController` for albums** — The existing controller serves different consumers with simpler needs. See Part 5 rationale. -- **Does not touch `album-dropdown.ts`** — Already a well-scoped 410-line sub-component. -- **Does not extract drag handlers** — ~165 lines of glue code that delegates to existing `drag-controller.ts`/`drag-image.ts`. Diminishing returns. - ---- - -## Part 6: Code Quality and Performance Improvements - -These improvements are applied during the extraction steps that touch the relevant code. They don't change behavior — they make the same behavior more efficient and clean. - -### 6a.

Keep the 3 `console.error` (actual failures) and 1 `console.warn` (retry exhaustion). - -**Applied during:** Part 3 (scroll-manager extraction) and Part 5 lifecycle cleanup. - -### 6b. Memoize `buildGridEntries()` — eliminates 3-5 redundant array allocations per render - -**Problem:** `buildGridEntries()` allocates a new `GridEntry[]` array on every call. In split-mode rendering, it's called up to 5 times per render cycle: -- `getBeforeEntries()` → `buildGridEntries().slice(0, splitIndex)` (line 2003) -- `getAfterEntries()` called **twice** in `renderSplitGrid()` — once for `.length > 0` check (line 3612), once for `.items` (line 3616) — each rebuilding the full array -- `onVisibilityChanged` scroll handler also rebuilds it (line 1637) - -There's even a placeholder comment on line 340: `// buildGridEntries() memoization cache.` — but no cache was ever implemented. - -**Action:** -1. Cache the `GridEntry[]` result, keyed on `cachedFilteredAlbums` reference identity. Invalidate in `recomputeAlbumCache()`. -2. In `renderSplitGrid()`, compute `const afterEntries = this.getAfterEntries()` once and reuse for both the length check and the `.items` binding. - -**Applied during:** Part 1 (types — `GridEntry` moves) and main file cleanup. - -### 6c. Cache expanded album index — eliminates 6 redundant O(n) scans - -**Problem:** `cachedFilteredAlbums.findIndex((a) => a.ID === this.expandedAlbumId)` appears at 6 call sites (lines 1077, 1364, 1813, 1919, 1959, 2276). Each is a linear scan of the album array for the same ID. - -**Action:** Compute `expandedAlbumIndex` in `recomputeAlbumCache()` (or in `willUpdate` when `expandedAlbumId` changes). All 6 call sites become a direct property read. Invalidate when either `expandedAlbumId` or `cachedFilteredAlbums` changes. - -**Applied during:** Part 3 (scroll-manager extraction — 4 of the 6 sites are in scroll code) and main file cleanup. - -### 6d. Build `albumById` Map for O(1) selection lookups - -**Problem:** `getSelectedAlbumFilePaths()` (line 2401) and `warmAlbumFilePathCache()` (line 2472) both call `this.albums.filter(a => selectedAlbums.has(a.ID))` to find selected albums — an O(n) scan of the full album list. `resolveTrackCoverArt()` (line 3181) does `this.albums.find(a => a.Name === albumName)` — an O(n) name-based scan that could also match the wrong album if names collide. - -**Action:** Build a `Map` (keyed by album ID) when `albums` changes. Selection lookups iterate `selectedAlbums` and do O(1) map lookups. `resolveTrackCoverArt()` uses the map with `expandedAlbumId` instead of name-based search. - -**Applied during:** Part 5 (album-selection extraction). - -### 6e. Remove unnecessary `@state()` from 2 properties - -**Problem:** 15 properties have `@state()`. Two don't need it: -- `playlistFilePaths` (line 695) — only rendered inside the playlist submenu, which is conditionally shown when `playlistSubmenuOpen` is true. Since `showPlaylistSubmenu()` sets `playlistFilePaths` before setting `playlistSubmenuOpen`, the reactive update from `playlistSubmenuOpen` will render with the correct paths. `playlistFilePaths` itself doesn't need to trigger a re-render. -- `splitIndex` (line 737) — only used to compute `getBeforeEntries()`/`getAfterEntries()`. It's always set before `splitMode` changes (which triggers the render), so it doesn't need independent reactivity. - -**Action:** Remove `@state()` decorator from both. Make them plain private fields. - -**Applied during:** Main file cleanup after extractions. - -### 6f. Single-pass `onGridClick` path traversal - -**Problem:** `onGridClick` (line 3071) calls `composedPath()` once, then iterates it twice with `.some()` — once for `.album-card` and once for `.album-dropdown`. - -**Action:** Single loop checking both classes: -```typescript -for (const el of e.composedPath()) { - if (!(el instanceof HTMLElement)) continue; - if (el.classList.contains('album-card') || - el.classList.contains('album-dropdown')) return; -} -``` - -**Applied during:** Main file cleanup. - -### 6g. Use expanded album directly for cover art resolution - -**Problem:** `resolveTrackCoverArt(albumName)` (line 3176) does an O(n) `.find()` on `this.albums` by `Name` to get cover art URLs. But we already know which album is expanded (`expandedAlbumId`), and all tracks in the dropdown belong to that album. Name-based lookup has a theoretical collision risk if two albums share the same name. - -**Action:** Replace the name-based search with a direct lookup using `expandedAlbumId` and the `albumById` map from improvement 6d. Falls back gracefully if the album isn't found. - -**Applied during:** Part 5 (album-selection extraction) or main file cleanup. - -### 6h. Prune `albumFilePathCache` to prevent unbounded growth - -**Problem:** The `albumFilePathCache` (Map) is warmed when albums are selected and read during dragstart, but entries are never removed. Over a session, it grows without bound. - -**Action:** -1. Clear the entire cache when `albums` changes (library rescan). -2. After `warmAlbumFilePathCache()` completes, remove entries whose album ID is no longer in `selectedAlbums`. - -**Applied during:** Part 5 (album-selection extraction — the cache moves to `AlbumSelectionManager`). - ---- - -## Execution Order - -| Step | File(s) | Risk | Notes | -|------|---------|------|-------| -| 1 | `cover-grid-types.ts` | Minimal | Pure move, no logic changes | -| 2 | `cover-grid-styles.ts` | Minimal | Pure move, verify `static styles` array works | -| 3 | `utils/context-menu-controller.ts` | Medium | Widest blast radius — update 6 components | -| 4 | `album-selection.ts` + improvements 6d, 6g, 6h | Low | Contained to cover-grid | -| 5 | `scroll-manager.ts` + improvements 6a, 6c | Medium | Largest extraction, deep state interaction | -| 6 | Main file cleanup: improvements 6b, 6e, 6f | Low | After extractions, clean up remaining code | -| 7 | Verify: `pnpm build` + `pnpm exec tsc --noEmit` | — | Ensure no type errors or build failures | - -Steps 1-2 are safe warmups.

Fix `InsertNext` empty-queue bug - -**Location:** `queue.go:991-1041` (current) - -**Problem:** `InsertNext` does not handle the empty-queue case. When called on an empty queue: -- `insertPos = currentIndex + 1 = 0 + 1 = 1` (out of bounds clamped to 0 by the guard) -- A track is inserted, but `currentIndex` stays at 0 and `loadCurrentTrack` is never called -- The user sees a queue with one track but nothing loaded - -Compare with `InsertNextTracks` (line 977-980) which correctly checks `wasEmpty` and loads the first track. - -**Fix:** Add after the persist calls in `InsertNext`: -```go -wasEmpty := len(q.tracks) == 0 -// ... existing insert logic ... -// After commitMutation: -if wasEmpty && len(q.tracks) > 0 { - q.currentIndex = 0 - q.loadCurrentTrack() -} -``` - -### 2b. Fix `AddTracks` persist-before-index ordering - -**Location:** `queue.go:906-912` (current) - -**Problem:** `AddTracks` calls `persistTracks()` + `persistState()` at lines 906-907, then sets `currentIndex = 0` and calls `loadCurrentTrack()` at lines 909-912. If the app crashes between persist and index update, the restored state has the wrong `currentIndex`. `AddTrack` does this correctly (sets index before persist). - -**Fix:** Move the `wasEmpty` check and `currentIndex = 0` assignment to before the `commitMutation()` call, matching the pattern in `AddTrack`. - ---- - -## Part 3: DRY Improvements (behavior-preserving) - -### 3a. Extract `toStringSlice` and `toIntSlice` helpers (in `handlers.go`) - -**Problem:** The `[]interface{} -> []string` conversion is copy-pasted in 4 handlers (`handleSetQueue`, `handleAddTracksToQueue`, `handleInsertTracksAtIndex`, `handlePlayTracksNext`). The `[]interface{} -> []int` conversion is in 2 handlers (`handleRemoveTracksFromQueue`, `handleMoveQueueTracks`). - -**New helpers:** -```go -// toStringSlice extracts strings from a Wails event argument. -func toStringSlice(raw []interface{}) []string { - result := make([]string, 0, len(raw)) - for _, v := range raw { - if s, ok := v.(string); ok { - result = append(result, s) - } - } - return result -} - -// toIntSlice extracts ints (from float64) from a Wails event argument. -func toIntSlice(raw []interface{}) []int { - result := make([]int, 0, len(raw)) - for _, v := range raw { - if f, ok := v.(float64); ok { - result = append(result, int(f)) - } - } - return result -} -``` - -Eliminates ~30 lines of repetition, centralizes type-coercion logic. - -### 3b. Extract `trackMeta.toTrack(position)` method (in `queue.go`) - -**Problem:** The `trackMeta` -> `Track` struct literal appears 7 times across `SetQueue`, `resolveRemainingTracks`, `AddTrack`, `AddTracks`, `InsertNextTracks`, `InsertNext`, `InsertTracksAt`. - -**New method:** -```go -// toTrack converts metadata lookup results into a queue Track. -func (m trackMeta) toTrack(position int64) Track { - return Track{ - AudioFileID: m.AudioFileID, - FilePath: m.FilePath, - Position: position, - Title: m.Title, - Artist: m.Artist, - } -} -``` - -Eliminates ~35 lines. Creates one authoritative mapping point — if a field is added to `Track`, only one place needs updating. - -### 3c. Extract `commitMutation(reindex bool)` helper (in `queue.go`) - -**Problem:** The post-mutation epilogue (reindex positions → regenerate shuffle order → persist tracks → persist state) is repeated in 8+ methods: `InsertNextTracks`, `InsertNext`, `InsertTracksAt`, `MoveQueueTracks`, `RemoveTrack`, `RemoveTracks`, `AddTracks`, `SetQueue` (small-batch path), `AddTrack` (after unification). - -**New helper:** -```go -// commitMutation persists the current queue state after a mutation. -// When reindex is true, track positions are renumbered first. -func (q *Queue) commitMutation(reindex bool) { - if reindex { - q.reindexPositions() - } - if q.shuffleMode { - q.generateShuffleOrder() - } - q.persistTracks() - q.persistState() -} -``` - -Eliminates ~40 lines. Ensures every mutation consistently applies the full epilogue — no risk of forgetting one of the steps. - -### 3d. Use `slices.Insert` for slice insertions (in `queue.go`) - -**Problem:** The manual tail-copy insertion pattern appears 3 times: -```go -tail := make([]Track, len(q.tracks[insertPos:])) -copy(tail, q.tracks[insertPos:]) -q.tracks = append(q.tracks[:insertPos], newTracks...) -q.tracks = append(q.tracks, tail...) -``` -in `InsertNextTracks`, `InsertTracksAt`, and `MoveQueueTracks`. `InsertNext` has a variant. - -**Fix:** Replace all with `q.tracks = slices.Insert(q.tracks, insertPos, newTracks...)`. The `slices` package is already imported. - -### 3e. Unify `AddTrack` persistence strategy (in `queue.go`) - -**Problem:** `AddTrack` is the only method that uses a single-row `InsertQueueTrack` DB call (line 834), while every other mutating method uses `persistTracks` (full table rewrite). This dual strategy means: -- If the single-row insert fails, the in-memory state diverges from the DB -- `AddTrack` has different error recovery behavior than all other methods -- The shuffle order append (line 847) is an optimization that `AddTracks` doesn't share, creating inconsistency - -**Fix:** Replace `AddTrack`'s custom DB insert with `commitMutation(false)` (no reindex needed since it appends). This makes it consistent with every other method. The performance cost of a full table rewrite for a single-track add is negligible for music-player queue sizes (typically <10K tracks). - ---- - -## Part 4: Cleanup (bundled from catalog #14 and #18) - -### 4a. Delete `sortInts`, use `slices.Sort` (catalog #18) - -**Location:** `queue.go:1274-1281` (current) - -Delete the hand-rolled insertion sort. Replace its one call site in `MoveQueueTracks` (`sortInts(sorted)` → `slices.Sort(sorted)`). `slices.Sort` is already used elsewhere in the same file (line 1364). - -### 4b. Remove exported `PlayFromStart` wrapper - -**Location:** `queue.go:1521-1530` (current) - -`PlayFromStart` is exported but has zero callers outside the package. The unexported `playFromStart` already exists. Remove the exported wrapper — if external access is ever needed, it can be re-added. - ---- - -## Execution Order - -The order matters because later steps depend on earlier ones: - -1. **Replace `sortInts` with `slices.Sort`** — single-line change, eliminates a function before the split -2. **Remove `PlayFromStart`** — eliminates dead code before the split -3. **Add `trackMeta.toTrack()` method** — replace all 7 call sites -4. **Add `commitMutation()` helper** — replace all 8+ call sites -5. **Fix `InsertNext` empty-queue bug** — add `wasEmpty` guard -6. **Fix `AddTracks` persist ordering** — move index assignment before persist -7. **Unify `AddTrack` persistence** — replace custom insert with `commitMutation` -8. **Use `slices.Insert`** — replace 3-4 manual insertion patterns -9. **Extract `handlers.go`** — move `OnPlaybackFinished`, `registerEventHandlers`, all `handle*` methods; add `toStringSlice`/`toIntSlice` helpers; update all 6 call sites -10. **Extract `emit.go`** — move all 4 `emit*` methods -11. **Extract `navigation.go`** — move all 6 navigation/shuffle functions -12. **Extract `persistence.go`** — move all 7 persistence/lookup functions -13. **Clean up `queue.go` imports** — remove now-unused imports (`encoding/json`, `fmt`, `strings`, `math/rand/v2`, `errors`, `yellowjacket/backend/events`, `yellowjacket/backend/database/sql/sqlcgen`) -14. **Delete `ErrEmptyQueue` and `ErrNoPlayer`** — unused sentinels (catalog #14) -15. **Run `make lint`** — fix any formatting/import-order issues -16. **Run `make test`** — verify nothing is broken (note: no queue-specific tests exist, but this catches compilation errors and any tests that depend on queue indirectly) -17. **Update refactoring catalog** — mark #3, #14, #18 as solved - -## Risk Assessment - -**Very low risk.** All files remain in the same `queue` package — field access, unexported methods, and mutex sharing work identically across files within a package. The Go compiler catches any missing imports or broken references at build time. The two bug fixes change behavior only in edge cases that are currently broken. The DRY extractions are mechanical transformations that preserve identical behavior. - -## What This Does NOT Change - -- No changes to the public API surface (except removing unused `PlayFromStart` and the unused sentinels) -- No changes to the mutex strategy or locking granularity -- No changes to the event system or frontend -- No changes to database schema or query logic -- No new dependencies diff --git a/backend/player/player.go b/backend/player/player.go index b49cdb1..f2cb98a 100644 --- a/backend/player/player.go +++ b/backend/player/player.go @@ -64,6 +64,26 @@ const ( Stopped State = "stopped" ) +// TrackInfo contains metadata and playback state for the currently +// loaded track.

15 `Request*` events (frontend→backend) with direct Wails bindings while keeping the 4 backend→frontend push events (`QueueChanged`, `QueueIndexChanged`, `QueueModeChanged`, `QueueTracksModified`) intact. This eliminates ~420 lines of handler boilerplate in Go and aligns the queue's communication pattern with playlists. + +## Rationale + +**Why bindings for frontend→backend (replacing events):** +- Eliminates 420 lines of hand-written type-assertion boilerplate in `handlers.go` +- Provides compile-time type safety — Wails auto-generates typed TypeScript bindings from Go method signatures, so `float64`→`int` casting, `[]interface{}`→`[]string` conversion, and `len(data)` validation all disappear +- Adding a new queue operation becomes a 1-file change (add Go method) vs the current 4-file change (Go event constant, TS event constant, Go handler, TS store method) +- Aligns with the playlist pattern, reducing cognitive overhead + +**Why keep events for backend→frontend (not replacing with invalidate-and-refetch):** +- The queue's delta system (`QueueTracksModified` with add/insert/remove/move actions) is genuinely good architecture for a data structure that changes frequently during playback +- Avoids unnecessary round-trips — the backend pushes only what changed +- The playlist's invalidate-and-refetch pattern works for playlists (infrequent mutations) but would be wasteful for a queue (changes on every track advance) + +## Prerequisites + +The queue must be created in `NewYellowJacketApp()` (before `wails.Run()`) rather than in `OnStartup()`, because Wails v2 consumes the `Bind` slice eagerly at startup via reflection. The struct pointer must be non-nil and fully constructed at `Bind` time. + +This is safe because `queue.NewQueue()` only needs `logger` and `db` (both already available in `NewYellowJacketApp`). The player dependency and context are set later via `SetPlayer()` and `SetContext()` during `OnStartup`, which is the existing two-phase initialization pattern used by all other bound services. + +## Detailed Steps + +### Step 1: Move queue construction to `NewYellowJacketApp` and add to `FEBindings` + +**File:** `backend/app.go` + +In `NewYellowJacketApp()`, after the playlist service is created (~line 104), add: + +```go +yjApp.queue = queue.NewQueue(yjApp.logger, yjApp.database) +``` + +Add the queue to `FEBindings`: + +```go +yjApp.FEBindings = []any{ + yjApp.FrontendUtil, + yjApp.appConfig, + yjApp.library, + yjApp.playlist, + yjApp.queue, +} +``` + +In `OnStartup()`, remove `queue.NewQueue(...)` and keep only the deferred initialization: + +```go +yj.queue.SetContext(ctx) +yj.queue.SetPlayer(yj.player) +yj.queue.RestoreState() +``` + +### Step 2: Remove `registerEventHandlers()` and all handler boilerplate + +**File:** `backend/queue/handlers.go` + +Remove: +- `registerEventHandlers()` — all 16 `runtime.EventsOn` registrations (lines 41-172) +- All 10 `handle*` functions (lines 201-461): `handleSetQueue`, `handleAddToQueue`, `handlePlayNext`, `handleRemoveFromQueue`, `handleRemoveTracksFromQueue`, `handleAddTracksToQueue`, `handleInsertTracksAtIndex`, `handleMoveQueueTracks`, `handlePlayQueueIndex`, `handlePlayTracksNext` +- The two helper functions `toStringSlice` and `toIntSlice` (lines 175-199) + +Keep: +- `OnPlaybackFinished()` (lines 11-38) — this is domain logic, not event boilerplate + +**File:** `backend/queue/queue.go` + +In `SetContext()`, remove the call to `q.registerEventHandlers()`. The method becomes: + +```go +func (q *Queue) SetContext(ctx context.Context) { + q.ctx = ctx +} +``` + +### Step 3: Remove the 15 `Request*` queue event constants + +**File:** `backend/events/events.go` + +Remove from the "Queue events" const block (lines 38-52): +- `RequestNext` +- `RequestPrevious` +- `RequestSetQueue` +- `RequestAddToQueue` +- `RequestPlayNext` +- `RequestRemoveFromQueue` +- `RequestToggleShuffle` +- `RequestCycleRepeat` +- `RequestAddTracksToQueue` +- `RequestPlayTracksNext` +- `RequestPlayQueueIndex` +- `RequestRemoveTracksFromQueue` +- `RequestInsertTracksAtIndex` +- `RequestMoveQueueTracks` +- `RequestClearQueue` + +Keep `RequestPlay` — it's in the "Playback control events" block and is used by the queue's event handler.

But check if `RequestPlay` is still used by the player package first. + +> **Note:** `RequestPlay` is currently handled by the queue (in `handlers.go:48`), not the player. After this refactor, the queue's `Play()` method will be callable directly via bindings, so the `RequestPlay` event handler in the queue is no longer needed. However, `RequestPlay` may still be emitted by the frontend for player-related actions — audit all `RequestPlay` usages before removing the constant. + +**File:** `frontend/src/events.ts` + +Remove the corresponding 15 `Request*` constants from lines 28-42. Keep the 4 backend→frontend queue events (lines 24-27). + +### Step 4: Rewrite the queue store to use Wails bindings + +**File:** `frontend/src/store/queue-store.ts` + +Replace the 14 action methods that call `EventsEmit(Events.Request*)` with direct calls to the auto-generated Wails bindings. + +**Before** (example): +```typescript +import { EventsOn, EventsEmit } from '@runtime/runtime'; +import { Events } from '../events'; + +// ... +next(): void { + EventsEmit(Events.RequestNext); +} + +setQueue(filePaths: string[], startIndex: number, shuffleStart = false): void { + EventsEmit(Events.RequestSetQueue, filePaths, startIndex, shuffleStart); +} +``` + +**After** (example): +```typescript +import { EventsOn } from '@runtime/runtime'; +import { Events } from '../events'; +import * as QueueService from '@go/queue/Queue'; + +// ... +next(): void { + QueueService.Next(); +} + +setQueue(filePaths: string[], startIndex: number, shuffleStart = false): void { + QueueService.SetQueue(filePaths, startIndex, shuffleStart); +} +``` + +Keep the entire `initializeEventListeners()` method unchanged — the 4 backend→frontend event subscriptions (`QueueChanged`, `QueueIndexChanged`, `QueueModeChanged`, `QueueTracksModified`) and the `applyTracksDelta()` logic remain as-is. + +Remove the `EventsEmit` import if no longer needed after removing all `Request*` emissions. + +**Complete action method mapping** (queue store method → Wails binding): + +| Store method | Current event | Wails binding call | +|---|---|---| +| `next()` | `RequestNext` | `QueueService.Next()` | +| `previous()` | `RequestPrevious` | `QueueService.Previous()` | +| `setQueue(filePaths, startIndex, shuffleStart)` | `RequestSetQueue` | `QueueService.SetQueue(filePaths, startIndex, shuffleStart)` | +| `addToQueue(filePath)` | `RequestAddToQueue` | `QueueService.AddTrack(filePath)` | +| `playNext(filePath)` | `RequestPlayNext` | `QueueService.InsertNext(filePath)` | +| `removeFromQueue(position)` | `RequestRemoveFromQueue` | `QueueService.RemoveTrack(position)` | +| `removeTracksFromQueue(positions)` | `RequestRemoveTracksFromQueue` | `QueueService.RemoveTracks(positions)` | +| `addTracksToQueue(filePaths)` | `RequestAddTracksToQueue` | `QueueService.AddTracks(filePaths)` | +| `playTracksNext(filePaths)` | `RequestPlayTracksNext` | `QueueService.InsertNextTracks(filePaths)` | +| `toggleShuffle()` | `RequestToggleShuffle` | `QueueService.ToggleShuffle()` | +| `cycleRepeat()` | `RequestCycleRepeat` | `QueueService.CycleRepeat()` | +| `playAtIndex(index)` | `RequestPlayQueueIndex` | `QueueService.PlayIndex(index)` | +| `insertTracksAtIndex(filePaths, index)` | `RequestInsertTracksAtIndex` | `QueueService.InsertTracksAt(filePaths, index)` | +| `moveTracksInQueue(fromIndices, toIndex)` | `RequestMoveQueueTracks` | `QueueService.MoveQueueTracks(fromIndices, toIndex)` | +| `clearQueue()` | `RequestClearQueue` | `QueueService.Clear()` | + +> **Note:** Some store method names don't match Go method names (e.g., `addToQueue` → `AddTrack`, `playNext` → `InsertNext`). The store method names can remain unchanged for API stability — only the implementation changes. + +### Step 5: Handle `Play()` specifically + +The queue's `Play()` method is currently triggered by the `RequestPlay` event, which is in the "Playback control events" group and is also emitted by `player-controls.ts`. After this refactor: + +- The `RequestPlay` event handler in `handlers.go:48` is removed along with all other handlers +- The frontend should call `QueueService.Play()` directly instead of `EventsEmit(Events.RequestPlay)` + +Audit all places that emit `RequestPlay`: +- `frontend/src/components/audio-player/controls/player-controls.ts` — the play button emits `RequestPlay`. This should be changed to call `QueueService.Play()` (or more likely, the queue store should expose a `play()` method that delegates to the binding) + +If `RequestPlay` has no other consumers after this change, remove the event constant from both `events.go` and `events.ts`. + +### Step 6: Regenerate Wails bindings + +Run `wails generate module` (or `make dev` which triggers binding generation) to produce the auto-generated files: + +- `frontend/wailsjs/go/queue/Queue.js` — JavaScript bridge calling `window['go']['queue']['Queue'][method](...)` +- `frontend/wailsjs/go/queue/Queue.d.ts` — TypeScript declarations with proper types +- `frontend/wailsjs/go/models.ts` — Updated with `queue.Track`, `queue.State`, `queue.RepeatMode`, etc. + +> **Important:** The auto-generated TypeScript types will mirror the Go struct JSON tags, so the frontend types already defined in `queue-store.ts` (`QueueTrack`, `QueueState`, `IndexChanged`, `ModeChanged`, `TracksModified`) will have matching auto-generated equivalents in `models.ts`. We should keep the manually-defined types in the store (they're used by the event listeners which still need them) but could optionally import the model types where convenient. + +### Step 7: Handle `SetContext` visibility + +When a struct is added to Wails `FEBindings`, **all exported methods** become callable from JavaScript. `SetContext(ctx context.Context)` and `SetPlayer(player TrackLoader)` would be exposed, which is undesirable — they're internal lifecycle methods, not frontend API. + +Options: +1. **Unexport them** — rename to `setContext`/`setPlayer`. This requires updating `app.go` to call `q.setContext(ctx)` etc. But unexported methods on structs in other packages aren't accessible, so this won't work without making them package-internal. +2. **Create a thin facade struct** — a `Service` (or `API`) struct that embeds or wraps `*Queue` and only exposes the methods the frontend should call. This is the playlist pattern (`playlist.Service`). +3. **Accept the exposure** — Wails will generate bindings for `SetContext` and `SetPlayer`, but the frontend simply won't call them. They'll be inert in the generated JS. This is what happens with `playlist.Service.SetContext` — it's in the generated `Service.js` but never imported by the frontend. + +**Recommendation:** Option 3 — accept it. The playlist already has `SetContext` exposed in its generated bindings (`frontend/wailsjs/go/playlist/Service.js:69`) and it's not a problem. Wails bindings are not a security boundary (the frontend and backend are in the same process). The generated bindings are auto-generated artifacts, not a public API. No one will accidentally call `SetContext` from the frontend. + +If `SetPlayer` is a concern because `TrackLoader` is an interface type that Wails can't serialize, Wails may skip it or error during binding generation. If so, either unexport `SetPlayer` only, or have `app.go` set it via an unexported package-level function. This needs testing during step 6. + +### Step 8: Update `queue-controller.ts` (no changes needed) + +The `QueueController` (`frontend/src/store/controllers/queue-controller.ts`) proxies all actions through `queueStore.*()`. Since we're only changing the store's internal implementation (from `EventsEmit` to binding calls), the controller needs zero changes.

All data flows through the event system. - ---- - -## Problem Statement - -`player.getCurrentTrackInfoLocked()` returns `map[string]interface{}` — a stringly-typed map with 10 keys. Then `emitTrackChanged()` mutates this map by bolting on 3 additional keys (`trackLength`, `seekPosition`, `trackChangeId`) before emitting it via `runtime.EventsEmit`. This pattern has several issues: - -1. **No compile-time safety** — a typo like `"fileName"` vs `"filename"` is a silent bug. -2. **Split construction** — the 13-field payload is built in two places (`getCurrentTrackInfoLocked` builds 10 fields, `emitTrackChanged` appends 3 more via map mutation). The shape of the data is not visible in any single location. -3. **Inconsistent nil-file fallback** — when `p.currentFile == nil`, the returned map has 7 keys (missing `coverArtSmall`, `coverArtMedium`, `coverArtLarge`). The error fallback in `emitTrackChanged` has only 3 keys. Both cases produce maps with incomplete field sets that differ from each other and from the happy path (13 keys). -4. **Missed opportunity for Wails type generation** — if the player were ever added to `FEBindings`, a struct return type would auto-generate TypeScript bindings. Currently the frontend manually maintains a `TrackInfo` interface that must be kept in sync by hand. -5. **Contrast with rest of codebase** — the queue package already uses proper structs with JSON tags (`queue.Track`, `queue.State`, etc.) for all event payloads. The player is an outlier. - ---- - -## Design Decisions & Reasoning - -### Decision 1: Define a single `TrackInfo` struct (not two separate types) - -The catalog suggests defining a `TrackInfo` struct. A question arises: should `getCurrentTrackInfoLocked` return a "partial" struct (10 fields) while `emitTrackChanged` extends it with 3 more? No — the whole point is to eliminate the mutation pattern. A single struct with all 13 fields is cleaner. The struct represents "everything the frontend needs to know about the current track for the TrackChanged event." - -**Reasoning:** A single struct means one source of truth for the shape of the data. The zero values for `TrackLength`, `SeekPosition`, and `TrackChangeID` are naturally `0` in Go, which is semantically correct for "no track loaded" or "error" fallback cases. - -### Decision 2: Use `json` struct tags with camelCase keys - -The existing map uses camelCase keys (`"fileName"`, `"coverArtSmall"`, etc.). Wails serializes event payloads as JSON. The struct must use `json:"fileName"` tags to preserve the exact same wire format — otherwise the frontend would break. - -**Reasoning:** This is a behavioral requirement, not a style choice. The frontend `TrackInfo` interface expects camelCase keys. Changing them would require coordinated frontend changes for zero benefit. - -### Decision 3: Keep `getCurrentTrackInfoLocked` but change its return type - -Rather than inlining all logic into `emitTrackChanged`, keep the `getCurrentTrackInfoLocked` helper but have it return `TrackInfo` (with the base 10 fields populated). Then `emitTrackChanged` fills in the remaining 3 fields (`TrackLength`, `SeekPosition`, `TrackChangeID`) on the struct before emitting. - -**Reasoning:** This preserves the separation of concerns — "build metadata from file/DB" vs "compute playback position and emit." It also keeps `GetCurrentTrackInfo()` (the public method) useful: it returns the same struct, just without the playback-timing fields (which are zero-valued). If the player is ever added to `FEBindings`, this method's return type would auto-generate a TypeScript class. - -### Decision 4: Eliminate `GetCurrentTrackInfo()` public method — or keep it? - -`GetCurrentTrackInfo()` has **zero Go callers** and **zero TypeScript callers** (the player is not in `FEBindings`). It exists only as dead code. However, it was likely intended as a Wails binding that hasn't been wired up yet, and it could be useful in the future. - -**Decision: Keep it.** The cost of a single unused method is minimal, and it now returns a proper struct which would be useful if the player is added to `FEBindings` later. If desired, it can be removed as part of a separate cleanup (item #13 addresses dead player methods). - -### Decision 5: Fix the inconsistent nil-file/error fallbacks - -Currently: -- **nil file fallback** (line 840-848): returns 7 keys — missing `coverArtSmall`, `coverArtMedium`, `coverArtLarge` -- **error fallback** in `emitTrackChanged` (line 319-323): returns only 3 keys — missing most fields - -With a struct, both fallbacks naturally return a fully-populated struct (all fields present, most set to zero values). The `State` field should still be set explicitly in both cases. This eliminates the inconsistency for free. - -### Decision 6: Place the struct in the existing `player.go` file, not a new file - -The player package has only 3 files (`player.go`, `volume.go`, `player_test.go`). The struct is tightly coupled to the player — it describes what the player emits. Creating a separate `trackinfo.go` file for a single ~20-line struct definition would be premature file splitting for such a small package. - -**Reasoning:** Follow the existing pattern — `State` type and playback constants are already defined in `player.go`. The `TrackInfo` struct logically belongs alongside them. - -### Decision 7: Use `State` type (not `string`) in the struct - -Currently the map stores `string(p.state)` — explicitly converting the `State` type to `string`. The struct should use the `State` type with `json:"state"` tag. Since `State` is `type State string`, JSON serialization produces the same string value. This gives us type safety in Go without changing the wire format. - -**Reasoning:** The whole point of this refactoring is compile-time safety. Using `string` in the struct for the state field would undermine that goal. - -### Decision 8: Use `uint64` for `TrackChangeID` (match the field type) - -The `Player` struct defines `trackChangeID uint64`. The struct field should be `TrackChangeID uint64`. The frontend `TrackInfo` interface uses `number` which can safely represent integers up to 2^53 — more than sufficient for a monotonic counter that starts at 0 per session. - ---- - -## Implementation Plan - -### Step 1: Define the `TrackInfo` struct in `player.go` - -Add the struct definition near the existing `State` type (around line 58-65), after the sentinel errors: - -```go -// TrackInfo contains metadata and playback state for the currently loaded track. -type TrackInfo struct { - FileName string `json:"fileName"` - FilePath string `json:"filePath"` - State State `json:"state"` - Title string `json:"title"` - Artist string `json:"artist"` - Album string `json:"album"` - CoverArt string `json:"coverArt"` - CoverArtSmall string `json:"coverArtSmall"` - CoverArtMedium string `json:"coverArtMedium"` - CoverArtLarge string `json:"coverArtLarge"` - TrackLength int `json:"trackLength"` - SeekPosition int `json:"seekPosition"` - TrackChangeID uint64 `json:"trackChangeId"` -} -``` - -**Note:** `json:"trackChangeId"` (lowercase `d`) matches the existing frontend interface key `trackChangeId`. - -### Step 2: Refactor `getCurrentTrackInfoLocked` to return `TrackInfo` - -Change the signature from `(map[string]interface{}, error)` to `TrackInfo` (no error needed — see reasoning below). - -**Why remove the error return?** The current function never actually returns an error. It handles all error cases internally (DB lookup failure logs and falls back to defaults). The error in the return signature is unused dead weight. With a struct, the zero-value fallback is even cleaner. - -Updated implementation: - -```go -func (p *Player) getCurrentTrackInfoLocked() TrackInfo { - info := TrackInfo{ - State: p.state, - } - - if p.currentFile == nil { - return info - } - - info.FileName = filepath.Base(p.currentFile.Name()) - info.FilePath = p.currentFile.Name() - info.Title = info.FileName // default title - - if p.db != nil { - meta, err := p.db.Queries.GetTrackMetadataByPath( - p.ctx, info.FilePath, - ) - if err == nil { - if meta.Title != "" { - info.Title = meta.Title - } - - info.Artist = meta.Artist - info.Album = meta.Album - - if meta.CoverArtPath != "" { - base := filepath.Base(meta.CoverArtPath) - info.CoverArt = "/covers/" + base - info.CoverArtSmall = "/covers/" + - library.SizedFilename(base, "_sm") - info.CoverArtMedium = "/covers/" + - library.SizedFilename(base, "_md") - info.CoverArtLarge = "/covers/" + - library.SizedFilename(base, "_lg") - } - } else { - p.logger.Debug( - "Could not get track metadata from database", - "path", info.FilePath, "err", err, - ) - } - } - - return info -} -``` - -### Step 3: Update `GetCurrentTrackInfo` (public method) - -Change return type from `(map[string]interface{}, error)` to `TrackInfo`: - -```go -// GetCurrentTrackInfo returns information about the currently loaded track. -func (p *Player) GetCurrentTrackInfo() TrackInfo { - p.mu.Lock() - defer p.mu.Unlock() - - return p.getCurrentTrackInfoLocked() -} -``` - -**Note:** Dropping the error return is safe — there are zero callers of this method. - -### Step 4: Refactor `emitTrackChanged` to build the struct directly - -Replace map mutation with direct struct field assignment: - -```go -func (p *Player) emitTrackChanged() { - if p.ctx == nil { - p.logger.Error("Context is nil, cannot emit event") - - return - } - - trackInfo := p.getCurrentTrackInfoLocked() - - trackLengthSecs, err := p.trackLengthLocked() - if err != nil { - p.logger.Error("Cannot get track length") - } - - trackInfo.TrackLength = trackLengthSecs - - // Compute current seek position in seconds. - if p.seeker != nil { - speaker.Lock() - trackInfo.SeekPosition = p.seeker.Position() / - int(p.format.SampleRate) - speaker.Unlock() - } - - // Increment track change ID so the frontend can detect changes - // even when the same file plays consecutively. - p.trackChangeID++ - trackInfo.TrackChangeID = p.trackChangeID - - runtime.EventsEmit(p.ctx, events.TrackChanged, trackInfo) - - p.logger.Info( - "Emitting TrackChangedEvent with track info", - "trackInfo", trackInfo, - ) -} -``` - -**Key change:** No more error-fallback map with only 3 keys. If `getCurrentTrackInfoLocked()` returns a zero-valued struct (e.g., when no file is loaded), it still has all 13 fields — the frontend receives a complete, predictable shape every time. - -### Step 5: Verify `UnloadTrack` emits `nil` (no change needed) - -At `player.go:678`, `UnloadTrack` emits: -```go -runtime.EventsEmit(p.ctx, events.TrackChanged, nil) -``` - -This is correct and intentional — it signals "no track loaded" to the frontend, which handles `null` in `(trackInfo: TrackInfo | null) => { ... }`. No changes needed here. - -### Step 6: Run `make lint` and `make test` - -Ensure: -- No linting violations (line length, godot, nlreturn, etc.) -- Tests pass (the existing test is integration-only and skips in CI, but the build itself must succeed with `-tags webkit2_41`) - -### Step 7: (Optional) Update the frontend `TrackInfo` interface comments - -The frontend `TrackInfo` interface in `frontend/src/store/player-store.ts` already matches the struct fields exactly. No field changes are needed. However, a comment noting that it mirrors `player.TrackInfo` from the backend could be helpful for future maintainers: - -```typescript -// TrackInfo mirrors the player.TrackInfo struct in the Go backend. -// Fields are serialized as camelCase JSON via struct tags. -export interface TrackInfo { - // ... (existing fields, unchanged) -} -``` - ---- - -## Files Changed - -| File | Change | -|------|--------| -| `backend/player/player.go` | Add `TrackInfo` struct; refactor `getCurrentTrackInfoLocked`, `GetCurrentTrackInfo`, and `emitTrackChanged` | -| `frontend/src/store/player-store.ts` | Add comment noting Go struct mirror (optional) | - -**No other files need changes.** The frontend receives the data via events and the JSON wire format is identical (same keys, same types). No Wails binding regeneration is needed since the player is not in `FEBindings`. - ---- - -## Risks & Mitigations - -| Risk | Likelihood | Mitigation | -|------|------------|------------| -| JSON key mismatch after refactoring | Low | The `json` struct tags are set to exactly match the current map keys. Verify by running the app and checking the frontend receives correct data. | -| `slog` logging of struct differs from map | Very low | `slog` will log the struct fields. The output format changes but the information is equivalent. No functional impact. | -| Future addition of `player` to `FEBindings` | N/A | This refactoring *enables* that future change — Wails will auto-generate a `player.TrackInfo` TypeScript class from the struct. | - ---- - -## Verification - -1. `make lint` passes -2. `make build-dev` succeeds -3. Manual test: play a track, verify `now-playing` component shows correct title/artist/cover art -4. Manual test: verify seek bar shows correct track length and seek position -5.

Since we're removing `registerEventHandlers`, also remove `RequestPlay` from the queue's event handler. But check if `RequestPlay` is still used by the player package first. - -> **Note:** `RequestPlay` is currently handled by the queue (in `handlers.go:48`), not the player. After this refactor, the queue's `Play()` method will be callable directly via bindings, so the `RequestPlay` event handler in the queue is no longer needed. However, `RequestPlay` may still be emitted by the frontend for player-related actions — audit all `RequestPlay` usages before removing the constant. - -**File:** `frontend/src/events.ts` - -Remove the corresponding 15 `Request*` constants from lines 28-42.

The store method names can remain unchanged for API stability — only the implementation changes. - -### Step 5: Handle `Play()` specifically - -The queue's `Play()` method is currently triggered by the `RequestPlay` event, which is in the "Playback control events" group and is also emitted by `player-controls.ts`. After this refactor: - -- The `RequestPlay` event handler in `handlers.go:48` is removed along with all other handlers -- The frontend should call `QueueService.Play()` directly instead of `EventsEmit(Events.RequestPlay)` - -Audit all places that emit `RequestPlay`: -- `frontend/src/components/audio-player/controls/player-controls.ts` — the play button emits `RequestPlay`. This should be changed to call `QueueService.Play()` (or more likely, the queue store should expose a `play()` method that delegates to the binding) - -If `RequestPlay` has no other consumers after this change, remove the event constant from both `events.go` and `events.ts`. - -### Step 6: Regenerate Wails bindings - -Run `wails generate module` (or `make dev` which triggers binding generation) to produce the auto-generated files: - -- `frontend/wailsjs/go/queue/Queue.js` — JavaScript bridge calling `window['go']['queue']['Queue'][method](...)` -- `frontend/wailsjs/go/queue/Queue.d.ts` — TypeScript declarations with proper types -- `frontend/wailsjs/go/models.ts` — Updated with `queue.Track`, `queue.State`, `queue.RepeatMode`, etc. - -> **Important:** The auto-generated TypeScript types will mirror the Go struct JSON tags, so the frontend types already defined in `queue-store.ts` (`QueueTrack`, `QueueState`, `IndexChanged`, `ModeChanged`, `TracksModified`) will have matching auto-generated equivalents in `models.ts`. We should keep the manually-defined types in the store (they're used by the event listeners which still need them) but could optionally import the model types where convenient. - -### Step 7: Handle `SetContext` visibility - -When a struct is added to Wails `FEBindings`, **all exported methods** become callable from JavaScript. `SetContext(ctx context.Context)` and `SetPlayer(player TrackLoader)` would be exposed, which is undesirable — they're internal lifecycle methods, not frontend API. - -Options: -1. **Unexport them** — rename to `setContext`/`setPlayer`. This requires updating `app.go` to call `q.setContext(ctx)` etc. But unexported methods on structs in other packages aren't accessible, so this won't work without making them package-internal. -2. **Create a thin facade struct** — a `Service` (or `API`) struct that embeds or wraps `*Queue` and only exposes the methods the frontend should call. This is the playlist pattern (`playlist.Service`). -3. **Accept the exposure** — Wails will generate bindings for `SetContext` and `SetPlayer`, but the frontend simply won't call them. They'll be inert in the generated JS. This is what happens with `playlist.Service.SetContext` — it's in the generated `Service.js` but never imported by the frontend. - -**Recommendation:** Option 3 — accept it. The playlist already has `SetContext` exposed in its generated bindings (`frontend/wailsjs/go/playlist/Service.js:69`) and it's not a problem. Wails bindings are not a security boundary (the frontend and backend are in the same process). The generated bindings are auto-generated artifacts, not a public API. No one will accidentally call `SetContext` from the frontend. - -If `SetPlayer` is a concern because `TrackLoader` is an interface type that Wails can't serialize, Wails may skip it or error during binding generation. If so, either unexport `SetPlayer` only, or have `app.go` set it via an unexported package-level function. This needs testing during step 6. - -### Step 8: Update `queue-controller.ts` (no changes needed) - -The `QueueController` (`frontend/src/store/controllers/queue-controller.ts`) proxies all actions through `queueStore.*()`. Since we're only changing the store's internal implementation (from `EventsEmit` to binding calls), the controller needs zero changes. All 14 action proxy methods remain identical. - -### Step 9: Update components that call `queueStore` directly (no changes needed) - -These 6 components import `queueStore` and call its action methods: -- `player-controls.ts` — `queueStore.next()`, `.previous()`, `.toggleShuffle()`, `.cycleRepeat()` -- `track-list.ts` — `queueStore.setQueue()`, `.addTracksToQueue()`, `.playTracksNext()` -- `cover-grid.ts` — `queueStore.setQueue()`, `.addTracksToQueue()`, `.playTracksNext()` -- `genres-view.ts` — `queueStore.setQueue()`, `.addTracksToQueue()`, `.playTracksNext()` -- `artists-view.ts` — `queueStore.setQueue()`, `.addTracksToQueue()`, `.playTracksNext()` -- `playlist-view.ts` — `queueStore.setQueue()`, `.addTracksToQueue()`, `.playTracksNext()` - -Since the store's public API (method signatures) is unchanged, none of these components need modifications. - -**Exception:** `player-controls.ts` currently emits `Events.RequestPlay` directly for the play/pause button (not through the queue store). This specific call site needs to be updated to either: -- Call `queueStore.play()` (add a `play()` method to the store), or -- Call `QueueService.Play()` directly - -### Step 10: Run tests, lint, and build - -```bash -make test # Verify Go tests pass (especially queue tests) -make lint # Verify linting passes -cd frontend && pnpm exec tsc --noEmit # Verify TypeScript types -make build-dev # Full build to verify Wails binding generation works -``` - -## Files Modified - -| File | Action | Description | -|---|---|---| -| `backend/app.go` | Edit | Move queue construction; add to `FEBindings` | -| `backend/queue/handlers.go` | Major edit | Remove all `handle*` functions, `registerEventHandlers`, `toStringSlice`, `toIntSlice`.

These methods push the full current state to the frontend via events, ensuring stores are populated on app launch +- **State persistence**: Player state (volume, muted, last track, position) and queue state (tracks, index, modes) are persisted to SQLite.

The AGENTS.md documents this requirement +- Test coverage: No automated test verifies event name parity + +**Player Lock Ordering:** +- Files: `backend/player/player.go` lines 31-39 +- Why fragile: The player has two locks (its own `sync.Mutex` and the global `speaker.Lock()`) with a documented ordering requirement: "always acquire p.mu BEFORE speaker.Lock()". The `onPlaybackFinished` callback runs on a goroutine to avoid holding both locks simultaneously +- Safe modification: Never call `speaker.Lock()` while holding `p.mu` in a code path that could block. The `go p.onPlaybackFinished()` pattern in the beep callback (line 351) is critical — removing the goroutine dispatch would deadlock +- Test coverage: No test validates the lock ordering. The integration test requires hardware + +**Two-Phase Queue Initialization:** +- Files: `backend/queue/queue.go` lines 152-251 +- Why fragile: `SetQueue` uses a two-phase approach with generation counters to handle concurrent calls. The background goroutine (`resolveRemainingTracks`) must check the generation counter under the lock to avoid overwriting newer state +- Safe modification: Always increment `setQueueGen` before starting background work. Always check the counter both before and after acquiring the lock +- Test coverage: No unit test for concurrent SetQueue calls + +**Player SetContext Double Lock:** +- Files: `backend/player/player.go` lines 163-171 +- Why fragile: `SetContext` acquires and releases `p.mu` twice in succession. Between the two lock acquisitions, another goroutine could modify state +- Safe modification: Consider combining into a single lock acquisition, or document why the two-phase approach is intentional (it appears to be separating the context set from the state restore for clarity) +- Test coverage: Integration test only + +**Config TOML Serialization Roundtrip:** +- Files: `backend/config/config.go` lines 100-139, 142-160 +- Why fragile: `Load()` applies defaults, then decodes TOML over them, then validates. If a new config field is added without a proper default, existing config files will have the zero value. The `applyDefaults()` runs after decode which could overwrite valid zero values +- Safe modification: Always add defaults in `applyDefaults()` for new fields.

However, the Wails `EventsOn` API returns a cancel function that is never captured. If the architecture ever changes to non-singleton stores, this would leak +- Fix approach: Low priority — capture the cancel functions for documentation purposes even if they're never called + +**Library Store Potential Memory Pressure:** +- Issue: `libraryStore` caches the entire track, album, artist, and genre lists in memory simultaneously +- Files: `frontend/src/store/library-store.ts` lines 29-32 +- Impact: For a library with 100k+ tracks, this could be tens of MB of JavaScript objects. The eager fetch on construction (`eagerFetch()`) means all four datasets are loaded simultaneously +- Fix approach: Consider lazy loading per-view and releasing data for inactive views, or implementing virtual scrolling data providers that don't require holding the full dataset + +**Queue Store Delta Application Trusts Backend:** +- Issue: The `applyTracksDelta` method in `QueueStore` applies backend-sent delta operations without validation. If the frontend state diverges from the backend (e.g. missed event), the delta application produces incorrect state +- Files: `frontend/src/store/queue-store.ts` lines 107-171 +- Impact: Could cause visual glitches where the queue panel shows incorrect tracks or indices. The full-state `QueueChanged` event acts as a periodic correction mechanism +- Fix approach: Consider adding a sequence number or hash to detect state divergence and trigger a full re-sync + +## Dependencies at Risk + +**Wails v2 Framework Lock-in:** +- Risk: Wails v2 uses WebView2 (Windows), WebKit2 (Linux), WKWebView (macOS). The project requires `-tags webkit2_41` for Linux builds. Wails v3 is in active development with breaking API changes +- Impact: Migration to Wails v3 will require significant refactoring of the lifecycle management (`OnStartup`, `OnDomReady`, `OnShutdown`), event system, and binding registration +- Migration plan: Monitor Wails v3 stability. The event-based architecture and clean separation of concerns make migration more feasible than a tightly coupled approach + +**beep Audio Library:** +- Risk: The `gopxl/beep/v2` library handles all audio decoding and playback. It wraps platform-specific audio output (oto) and codec libraries. The speaker is initialized with global state (`speaker.Init`, `speaker.Lock`) +- Impact: The global speaker lock creates an implicit coupling between all audio operations.

The approach: + +- Backend: Add `GetTracksPage(offset, limit int)` and `GetTrackCount()` queries to sqlc +- Frontend: Replace `library.Track[]` with a `DataProvider` interface that the virtual scroller queries by range +- The existing virtual scrolling components (`track-list`, `cover-grid`) already render only visible rows — they just hold the full dataset backing array + +**Recommendation:** Start with Steps 1-3 (remove eager fetch). Measure. Only build Step 4 if data shows the full `GetAllTracks()` call is still a problem for the initial view.

Leaving them unfixed means the codebase has known race conditions, swallowed errors, and untested critical paths. + +| Improvement | Why Required | Complexity | Concern Ref | +|-------------|-------------|------------|-------------| +| **Fix SetContext data races in Queue, Library, Playlist** | `q.ctx`, `l.ctx`, `s.ctx` are written without locks but read under locks. This is a textbook data race detectable by `-race`. Even if startup ordering makes it safe today, any refactoring that changes init order silently introduces corruption. | LOW | Concurrency Concerns | +| **Fix package-level `startupErr` variable** | Mutable package-level variable shared between `OnStartup` and `OnDomReady`. Not thread-safe, untestable. Move to `YellowJacketApp` struct field. | LOW | Tech Debt | +| **Fix config file permissions (0o666 → 0o644)** | Writing world-writable config files is a security defect. One-line fix. | LOW | Error Handling Gaps | +| **Fix swallowed errors in MPRIS lifecycle callbacks** | `_ =` on `Pause()` and `Seek()` errors from OS media controls. Invisible failures. At minimum log; ideally emit frontend notification. | LOW | Error Handling Gaps | +| **Fix silently swallowed artist credit link error** | `_, _ = CreateArtistCreditArtist(...)` discards non-duplicate errors. Check error, ignore only UNIQUE constraint violations. | LOW | Error Handling Gaps | +| **Separate scan warnings from fatal errors** | `Scan()` returns `errors.Join()` of all errors. Callers cannot distinguish "scan completed with 3 file warnings" from "scan completely failed". Return warnings in metrics, fatal errors as the error return. | MEDIUM | Error Handling Gaps | +| **Unit tests for queue operations** | Queue is central to playback — SetQueue, navigation, shuffle, repeat, persistence — all untested. Bugs here cause tracks to skip, repeat wrong, or lose queue on restart. | HIGH | Test Coverage Gaps | +| **Unit tests for library scan logic** | Metadata processing, entity cache, orphan cleanup — all untested. Bugs silently drop tracks or create duplicates. | HIGH | Test Coverage Gaps | +| **Unit tests for database layer (FTS5, migrations)** | FTS5 edge cases (special chars, empty queries) and migration failures are completely untested. | MEDIUM | Test Coverage Gaps | +| **Unit tests for config (load/save roundtrip)** | Config corruption or silent settings loss on upgrade has no safety net. | MEDIUM | Test Coverage Gaps | + +#### Concurrency Fix Details + +**Pattern:** For `SetContext` race conditions, the fix is uniform across Queue, Library, and Playlist: + +```go +// BEFORE (Queue — race condition): +func (q *Queue) SetContext(ctx context.Context) { + q.ctx = ctx // no lock, but q.ctx read under q.mu elsewhere +} + +// AFTER (correct): +func (q *Queue) SetContext(ctx context.Context) { + q.mu.Lock() + defer q.mu.Unlock() + q.ctx = ctx +} +``` + +Player already does this correctly (locks around `p.ctx = ctx` in `SetContext`). Apply the same pattern to Queue, Library, and Playlist. For Library and Playlist which don't currently have a mutex, add one — or document the "set during startup only, before any concurrent access" contract with a comment and `// SAFETY:` annotation. + +**Recommendation:** Add a `sync.Mutex` to Library and Playlist. The cost is negligible, and it eliminates the `-race` detector finding permanently. Documenting "safe because startup ordering" is fragile — the next developer (or future-you) may change init order. *Confidence: HIGH — standard Go concurrency practice.* + +#### Testing Strategy Details + +**In-memory SQLite for DB-dependent tests:** Use `sql.Open("sqlite", ":memory:")` with the `modernc.org/sqlite` driver (already in deps).

Create `volume_test.go` with pure function tests. *Confidence: HIGH — standard Go testing pattern.* + +**Event-driven testing approach:** For packages that emit events, provide a test double or capture mechanism. Options: +1. Accept an `EventEmitter` interface (allows mock in tests) +2. Make event emission optional when `ctx == nil` (already partially the case — `emit` methods check for nil context) +3. Test state mutations independent of event emission + +**Recommendation:** Option 2 is already partially implemented. Lean into it: test queue/library state mutations without Wails context, verify state is correct, don't test event emission in unit tests. *Confidence: HIGH.* + +--- + +### Differentiators (Raises Quality Significantly) + +These improvements go beyond "not broken" to "genuinely well-engineered." They improve performance, maintainability, and user experience noticeably. + +| Improvement | Value Proposition | Complexity | Concern Ref | +|-------------|-------------------|------------|-------------| +| **Eliminate duplicated FTS5 JOIN query pattern** | Same 5-table JOIN repeated 5+ times across search functions. Schema changes require updating all copies. Extract into shared constant or consolidate into fewer sqlc queries. | MEDIUM | Code Quality | +| **Migrate raw SQL in queue persistence to sqlc** | `lookupChunk` and `insertTrackBatch` use `fmt.Sprintf` for batch operations. Use `sqlc.slice()` for lookups. Batch inserts can remain hand-crafted but documented. | MEDIUM | Code Quality | +| **Optimize library store — lazy loading instead of eager fetch** | `eagerFetch()` loads all tracks, albums, artists, genres simultaneously on startup. For 50k+ tracks, this is tens of MB of JS objects loaded before user sees anything. Load only the active view's data. | HIGH | Performance | +| **Optimize queue persistence — incremental updates** | Every add/remove/move does DELETE ALL + INSERT ALL. For a 5000-track queue, every single mutation rewrites the entire table. Use INSERT/DELETE for individual operations; reserve full rewrite for SetQueue. | MEDIUM | Performance | +| **Fix SetQueue Phase 2 redundant lookups** | Phase 2 re-fetches metadata for ALL file paths including those already resolved in Phase 1. Pass Phase 1 results to Phase 2, only lookup remaining paths. | LOW | Performance | +| **Extract testable player logic** | Volume conversion, state serialization, format detection — all testable without audio hardware. Currently locked inside Player struct behind hardware dependency. | LOW | Test Coverage | +| **Event name parity validation** | Event names must match exactly between Go and TypeScript. No compile-time or runtime verification. Add a build-time check (code generation or test). | LOW | Fragile Areas | +| **Polish UI transitions and visual consistency** | CSS transitions for panel open/close, list item hover states, loading skeletons. Makes the app feel responsive and intentional. | MEDIUM | UX | +| **Improve frontend rendering for large libraries** | Even with `lit-virtualizer`, store updates trigger re-renders. Optimize with `repeat()` directive keyed by stable IDs, memoized render functions, and avoiding full-array replacement on updates. | MEDIUM | Performance | + +#### FTS5 Query Consolidation Details + +**Current state:** The same JOIN pattern appears in: +1. `SearchFTS()` — 5 columns +2. `SearchFTSByFilename()` — 5 columns (same query, different WHERE) +3. `SearchFTSTracks()` — 16 columns (extended version) +4. `RebuildSearchIndex()` — 5 columns (INSERT INTO ... SELECT) +5. `migration2BasenameAndFTS()` — same pattern in migration + +**Recommended approach:** Create a SQL view for the common JOIN: + +```sql +CREATE VIEW IF NOT EXISTS track_metadata_view AS +SELECT + af.id AS audio_file_id, + af.file_path, + af.length_milliseconds, + COALESCE(r.name, '') AS title, + COALESCE(ac.text, '') AS artist, + COALESCE(rg.name, '') AS album, + r.track_number, + r.disc_number, + -- ... other fields +FROM audio_files af +LEFT JOIN recordings r ON af.recording_id = r.id +LEFT JOIN artist_credit ac ON r.artist_credit_id = ac.id +LEFT JOIN ( + SELECT recording_id, MIN(release_group_id) AS release_group_id + FROM release_group_recordings + GROUP BY recording_id +) rgr ON r.id = rgr.recording_id +LEFT JOIN release_groups rg ON rgr.release_group_id = rg.id; +``` + +Then search queries become `SELECT ... FROM search_index si JOIN track_metadata_view tmv ON tmv.audio_file_id = si.rowid WHERE search_index MATCH ?`. Single source of truth for the JOIN pattern. + +**Alternative:** Extract the JOIN clause as a Go string constant and compose queries from it. Less elegant but simpler to implement. + +**Recommendation:** Use the SQL view approach. SQLite views are essentially macros — no performance penalty. They can be referenced in sqlc queries. Add the view to the schema, then rewrite search queries against it. *Confidence: MEDIUM — SQLite views in sqlc need verification during implementation. The concept is sound, but sqlc's handling of views with FTS5 virtual tables may have edge cases.* + +#### Queue Persistence Optimization Details + +**Current pattern:** +``` +Every mutation → commitMutation() → persistTracks() → DELETE ALL + batch INSERT ALL +``` + +**Improved pattern:** +``` +AddTrack → INSERT single row + shift positions +RemoveTrack → DELETE single row + shift positions +MoveTrack → UPDATE positions for affected range +SetQueue / RestoreState → DELETE ALL + batch INSERT ALL (keep current) +``` + +The sqlc queries `InsertQueueTrack`, `RemoveQueueTrack`, `ShiftQueuePositionsDown`, `ShiftQueuePositionsUp` already exist but aren't used by `commitMutation()`. Wire them up for single-track operations. + +*Confidence: HIGH — the individual queries already exist in sqlc.* + +#### Library Store Lazy Loading Details + +**Current:** Constructor calls `eagerFetch()` → 4 parallel Wails binding calls → 4 full table scans with JOINs → all data in JS memory. + +**Improved pattern:** +```typescript +class LibraryStore { + // Load on first access, not constructor + async getTracks(): Promise { + if (this.tracks !== null) return this.tracks; + // ... existing lazy logic (already implemented!) + } + + // Remove eagerFetch() from constructor + constructor() { + EventsOn(Events.LibraryScanComplete, () => this.invalidate()); + this.loadCoverSize(); + // Don't call eagerFetch() — let components trigger loading + } +} +``` + +The store *already has* lazy loading logic in `getTracks()`, `getAlbums()`, etc. The only change needed is removing the `eagerFetch()` call from the constructor and from `invalidate()`. Components already call the async getters. The eager fetch is redundant. + +**For even larger libraries (100k+):** Consider pagination. Backend already returns full result sets — add `LIMIT/OFFSET` or cursor-based pagination to the sqlc queries. Frontend virtualizer already handles rendering — it just needs a data provider that fetches pages instead of the full list. + +*Confidence: HIGH — the lazy loading infrastructure already exists.* + +#### Frontend Performance Details + +**Already in place:** `@lit-labs/virtualizer` with `flow` layout for track-list and `grid` layout for cover-grid. This handles DOM virtualization. + +**Additional optimizations:** +1. **Use `repeat()` with stable keys for virtualized lists.** Lit's `repeat` directive reorders DOM nodes instead of recreating them when list order changes. Use `track.filePath` as key (unique, stable). +2. **Avoid full-array replacement in store updates.** When a scan completes, `invalidate()` sets `tracks = null` forcing a full refetch. Instead, diff the new data against cached data and apply deltas. For scan completion, a full invalidation is appropriate, but for queue mutations, use the delta protocol already in place (`applyTracksDelta`). +3. **Debounce store notifications.** When multiple store properties update in rapid succession (e.g., during scan), batch notifications using `queueMicrotask()` instead of notifying per-property. + +*Confidence: MEDIUM — `repeat()` performance gains depend on the update patterns. For initially sorted lists that rarely reorder, `map()` is equally fast. For the cover-grid with resize/reflow, `repeat()` is clearly beneficial.* + +--- + +### Anti-Features (Things to Deliberately NOT Do During Refactoring) + +| Anti-Pattern | Why Tempting | Why Problematic | What to Do Instead | +|-------------|-------------|-----------------|-------------------| +| **Splitting large files purely for line count** | `playlist.go` (1778 lines) and `library.go` (1328 lines) feel large. Some components exceed 2000 lines. | The project explicitly decided against cosmetic splitting (PROJECT.md: "No cosmetic file splitting"). Splitting for its own sake creates navigation overhead and can break logical grouping. | Extract only when it enables reuse (e.g., shared controllers) or fixes a real problem (e.g., testing). | +| **Adding a full ORM or query builder** | Raw SQL in `lookupChunk`/`insertTrackBatch` feels inconsistent with sqlc-generated code. | An ORM would fight the existing sqlc architecture. A query builder adds a dependency for 2-3 queries. The hand-crafted SQL is safe (parameterized) and performant. | Document the hand-crafted queries with `// SAFETY:` comments explaining why they're not in sqlc. Use `sqlc.slice()` where it fits. Accept that batch INSERT with dynamic row count is a legitimate sqlc gap for SQLite. | +| **Rewriting the event system** | Event names are fragile strings that must match between Go and TypeScript. A typed event system would be safer. | The current system works. A rewrite touches every component in both frontend and backend. The risk-to-reward ratio is terrible for a consolidation milestone. | Add a build-time parity check (a test or codegen script that compares event constants). Fix the symptom (fragility) not the architecture. | +| **Adding frontend unit tests for all components** | No frontend tests exist. The temptation is to add comprehensive Lit component testing. | Large Lit components (1400-2600 lines) are expensive to test in isolation. Testing requires JSDOM or a browser harness, Shadow DOM handling, and Wails binding mocks. The backend is the source of truth — frontend bugs are visual, not data-corruption. | Test frontend-only logic (search ranking, column sorting, selection controller) as pure function tests if extracted. Defer full component testing to a future milestone. | +| **Making all queue mutations atomic/transactional from Go to frontend** | The delta protocol between queue store and backend could diverge. Adding sequence numbers or full-state hashes seems robust. | The existing `QueueChanged` event already acts as periodic full-state correction. Adding a sequence protocol adds complexity to every mutation path for a problem that manifests as a temporary visual glitch, self-correcting on the next full emit. | Keep the existing delta + periodic full-state pattern. If divergence becomes a real problem (not theoretical), add a generation counter then. | +| **Over-engineering error types** | The project uses sentinel errors and `fmt.Errorf("%w")`. Defining custom error types with fields (e.g., `ScanError{File, Phase, Cause}`) seems more structured. | Custom error types add boilerplate for minimal benefit in a desktop app. The structured logging already captures context via slog key-value pairs. Error types shine in API servers where callers branch on error details — not here. | Keep sentinel errors for `errors.Is()` checks. Keep `fmt.Errorf("%w")` for wrapping with context. Use `errors.Join()` for accumulation. Separate warnings from fatal errors in scan results via the return signature, not error types. | +| **Adding connection pooling or health checks for SQLite** | PROJECT.md mentions "No Database Connection Pooling/Health Check" in missing features. | This is a desktop app with a local SQLite file and `SetMaxOpenConns(1)`. Connection pooling is meaningless. Health checks add complexity for a failure mode (corrupt SQLite file) that's better handled by "show error dialog, suggest DB reset." | Leave as-is. This was correctly scoped as out-of-scope in PROJECT.md. | +| **Wrapping the entire test suite in Docker for CI** | Integration tests require audio hardware. Docker could theoretically provide a virtual audio device. | Massive CI complexity for marginal benefit. The goal is to make unit tests work without hardware, not to make integration tests work in CI. | Extract testable pure logic. Run unit tests in CI. Keep integration tests as manual/local-only with `YELLOWJACKET_INTEGRATION=1`. | + +--- + +## Feature Dependencies + +``` +[Fix SetContext races] + └── (no deps — standalone fix) + +[Fix error handling gaps (MPRIS, artist credit, config perms)] + └── (no deps — standalone fixes) + +[Separate scan warnings from fatal errors] + └── (no deps — changes Library.Scan return signature) + +[Add in-memory SQLite test infrastructure] + └──requires──> [database.NewTestDB() helper] + └──enables──> [Queue unit tests] + └──enables──> [Library unit tests] + └──enables──> [Database layer tests] + └──enables──> [Config tests] + +[Extract testable player logic] + └── (no deps — pure function extraction) + └──enables──> [Player pure logic tests] + +[FTS5 query consolidation (SQL view)] + └──should-precede──> [Database layer tests] + (test the consolidated queries, not the duplicated ones) + +[Queue persistence optimization (incremental updates)] + └──should-precede──> [Queue unit tests] + (test the optimized persistence, not the DELETE-ALL pattern) + +[Library store lazy loading] + └── (no deps — remove eagerFetch() call) + +[SetQueue Phase 2 optimization] + └──requires──> [Queue unit tests] + (need tests to verify the optimization doesn't break resolution) + +[Event name parity validation] + └── (no deps — standalone build-time check) + +[UI polish / transitions] + └── (no deps — CSS-only or Lit reactive changes) + +[Frontend rendering optimization] + └──benefits-from──> [Library store lazy loading] + (less data in memory = faster re-renders) +``` + +### Dependency Notes + +- **Test infrastructure is the critical enabler:** Almost all other improvements benefit from having tests first (to verify refactoring safety) or should happen before tests (to test the right code).

HIGH (based on codebase analysis + established Go/SQLite patterns) + +## Critical Pitfalls + +### Pitfall 1: Refactoring Concurrency Without Tests Creates Invisible Regressions + +**What goes wrong:** +You fix a data race (e.g., adding `q.mu.Lock()` to `Queue.SetContext()`) and the fix itself introduces a deadlock because you didn't understand the full call graph. Alternatively, the race fix changes timing semantics that other code implicitly depended on (e.g., Phase 2 of `SetQueue` now acquires the lock at a different time relative to `playCurrentTrack()`). Because there are no tests, the regression only manifests during specific usage patterns — like quickly switching playlists while a background resolve is running. + +**Why it happens:** +The instinct is "add mutex → race fixed." But mutexes change scheduling behavior. In YellowJacket, the Player has a documented lock ordering (`p.mu` before `speaker.Lock()`), the Queue has a generation counter pattern with `setQueueGen`, and the beep callback dispatches to a goroutine. These are three interacting concurrency mechanisms. Adding a lock to one path changes how the other two paths interleave. + +**How to avoid:** +1. **Write characterization tests first for the non-racy behavior.** Before fixing the race in `Queue.SetContext()`, write tests that verify `SetQueue` → `resolveRemainingTracks` → `emitQueueChanged` produces correct results. These tests won't catch the race (they're single-goroutine), but they'll catch if your mutex addition breaks the non-concurrent path. +2. **Fix races in a specific order:** First fix `SetContext()` patterns (they're called once during startup, lowest risk). Then fix the Queue mutation paths. Leave the Player's dual-lock pattern for last — it's the most complex and already works correctly. +3. **Use `go test -race` on every change.** Build a test binary with `-tags webkit2_41 -race` and run it. The race detector will confirm fixes and catch new races. +4. **Map the lock acquisition graph before adding any mutex.** For each public method, trace which locks it acquires and which callbacks it invokes. The `onPlaybackFinished()` goroutine dispatch (player.go line 350) is the critical pattern — it exists specifically to break a lock cycle. + +**Warning signs:** +- App hangs/freezes after a refactoring change (deadlock) +- "Previous" or "Next" track skips incorrectly after rapid clicks +- Queue panel briefly shows wrong tracks then corrects itself +- `-race` flag reports on code paths you didn't change + +**Phase to address:** +Testing phase should come first — write tests for queue operations, then fix concurrency. Specifically: (1) characterization tests for queue, (2) fix SetContext races, (3) fix mutation races, (4) fix player double-lock. + +--- + +### Pitfall 2: SQLite In-Memory Tests Behave Differently From File-Based Production DB + +**What goes wrong:** +You write tests using `:memory:` SQLite and they pass. In production with a file-based WAL-mode database and `SetMaxOpenConns(1)`, the behavior differs. Common divergences: +- `:memory:` doesn't persist `PRAGMA foreign_keys = ON` across connections (each new connection starts with FK enforcement off) +- `:memory:` with `SetMaxOpenConns(1)` doesn't surface contention the way file-based does (because there's only one connection, it never blocks — same as production, but WAL checkpoint behavior differs) +- FTS5 `search_index` tokenization may behave differently if the test doesn't apply the same schema setup sequence as `NewDB()` +- `PRAGMA user_version` is per-connection for `:memory:`, so migration tests that open a second connection see version 0 + +**Why it happens:** +`:memory:` is faster and doesn't leave test artifacts, so it's the default choice. But SQLite's `:memory:` is a distinct database per connection, not per DSN. The production code opens a file with specific pragmas (`_busy_timeout=5000&_journal_mode=WAL`), `PRAGMA foreign_keys = ON`, and runs schema files in alphabetical order. Any test that doesn't replicate this sequence is testing a different database. + +**How to avoid:** +1. **Create a test helper that mirrors `NewDB()` exactly:** Open a temp file (`t.TempDir() + "/test.db"`), apply the same pragmas, run the same embedded schemas, run `runMigrations()`. Export a `NewTestDB(t *testing.T) *DB` helper. +2. **Use `t.TempDir()`** — Go cleans it up automatically. This is enforced by the `usetesting` linter already configured. +3. **Always set `PRAGMA foreign_keys = ON`** in the test helper — the production code does this, and cascade deletes (like `queue_tracks` → `audio_files`) depend on it. +4. **If you do use `:memory:` for pure unit tests** (testing a single query), use the DSN `file::memory:?cache=shared` and document that it won't test WAL behavior. + +**Warning signs:** +- Tests pass but `ON DELETE CASCADE` doesn't fire in production +- FTS5 queries return different results in tests vs. app +- Migration tests pass but real migrations fail on existing databases +- Queue persistence tests pass but tracks are lost on restart + +**Phase to address:** +First phase — the test infrastructure setup. `NewTestDB()` must be correct before any database tests are written. + +--- + +### Pitfall 3: Deadlock From Player mutex + speaker.Lock() Ordering Violation + +**What goes wrong:** +The Player has a critical invariant: always acquire `p.mu` before `speaker.Lock()`. The beep library's playback callback runs with the speaker lock held. If you refactor a method to call `speaker.Lock()` while holding `p.mu` in a way that blocks, and the callback tries to acquire `p.mu`, you get a classic ABBA deadlock: +- Goroutine 1: holds `p.mu`, waiting for `speaker.Lock()` +- Goroutine 2 (beep callback): holds speaker lock, goroutine dispatch calls `onPlaybackFinished()` which waits for `p.mu` + +Currently this is avoided by the `go p.onPlaybackFinished()` dispatch pattern (player.go line 350), which means the callback itself doesn't hold `p.mu` — it just launches a goroutine. But the `startPaused()` method (line 340-354) acquires `speaker.Lock()` while `p.mu` is held by the caller. This works because it's a non-blocking lock/unlock sequence — but if you move speaker operations into a new method without understanding the lock context, deadlock follows. + +**Why it happens:** +Refactoring moves code between methods. If you extract `startPaused()` into a helper or inline it into another method, you might accidentally change the lock nesting. The `speaker.Lock()/Unlock()` inside `startPaused()` is safe because it's called with `p.mu` held (correct ordering), but `speaker.Play()` on line 347 is called with `p.mu` held too — and that's where the callback is registered. If the callback fires immediately (e.g., for a zero-length stream), the goroutine dispatch is the only thing preventing deadlock. + +**How to avoid:** +1. **Never refactor player lock code without drawing the lock acquisition graph first.** Document which methods hold which locks at each point. +2. **Keep the `go p.onPlaybackFinished()` dispatch pattern.** Never change this to a direct call. Add a comment explaining why. +3. **Extract pure logic (volume math, state serialization) into lock-free functions** that can be tested independently. Don't extract methods that need to hold locks. +4. **Add a regression test** that rapidly calls `LoadFile` → `Play` → `LoadFile` → `Play` to exercise the callback timing. Even without hardware, this can be tested with a mock streamer. + +**Warning signs:** +- App freezes when track finishes naturally (not when user clicks Next) +- App freezes specifically when rapidly changing tracks +- `SIGQUIT` goroutine dump shows both `p.mu.Lock()` and `speaker.Lock()` in different goroutines' stacks + +**Phase to address:** +Player refactoring phase. Extract testable pure logic first, leave lock-sensitive code paths for last. Document the lock ordering invariant with a test that validates the goroutine dispatch pattern. + +--- + +### Pitfall 4: FTS5 Query Consolidation Breaks Search Ranking or Returns + +**What goes wrong:** +You consolidate the 5+ copies of the FTS5 JOIN pattern into a shared constant or query builder. The consolidated query subtly differs from one of the originals — maybe a `LEFT JOIN` becomes an `INNER JOIN`, or the `COALESCE` default changes from `''` to `NULL`, or the subquery for `release_group_recordings` uses `MAX` instead of `MIN`. Search results change: tracks without albums stop appearing, or ranking changes because FTS5's `rank` function scores differently when join columns are NULL vs empty string. + +**Why it happens:** +The 5 copies look identical but have small contextual differences. `SearchFTS` uses `ORDER BY rank`, `SearchFTSTracks` might have a different LIMIT, `RebuildSearchIndex` doesn't need the rank column at all. When consolidating, you pick one version as the "canonical" form and the others silently regress. Additionally, FTS5's ranking is sensitive to which columns contain data — a `COALESCE` that returns `''` instead of the actual NULL affects the `bm25()` algorithm differently. + +**How to avoid:** +1. **Write search tests BEFORE consolidating.** Test each current function with known data: a track with full metadata, a track with no artist, a track with no album, a track matched only by file path. Capture the exact result set and ranking order. +2. **Consolidate the JOIN clause only, not the full query.** Extract the `FROM ... JOIN` chain as a SQL fragment constant. Let each function keep its own SELECT, WHERE, and ORDER BY clauses. +3. **Verify FTS5 `INSERT INTO search_index` uses the same column values as the search queries.** If the index stores `COALESCE(r.name, '')` but the search query expects `r.name`, the match behavior differs. +4. **Run the consolidation as a pure refactor with zero-diff tests** — if any test changes results, the consolidation introduced a bug. + +**Warning signs:** +- Search returns fewer results than before +- Search ranking changes (previously top result now buried) +- Tracks with missing metadata (no artist, no album) disappear from search +- `RebuildSearchIndex` produces different results than incremental inserts + +**Phase to address:** +Database/code quality phase. Write FTS5 search tests first, then consolidate. + +--- + +### Pitfall 5: Eager-to-Lazy Library Loading Creates Visible UX Regression + +**What goes wrong:** +You change `libraryStore` from eager-fetching all data on construction to lazy-loading per view. The first time the user navigates to the tracks view, there's a loading delay that didn't exist before. The cover grid flickers as albums load in chunks. Worse: components that used synchronous `getCachedTracks()` (which previously always returned data because of eager fetch) now return `null` and render empty states. The user, who has been using this app daily with instant library display, perceives this as a regression. + +**Why it happens:** +The current `eagerFetch()` fires all four fetches (`getTracks`, `getAlbums`, `getArtists`, `getGenres`) in the constructor. By the time the user interacts, data is already cached. Switching to lazy loading means the first interaction hits an async boundary. Every component that calls `getCachedTracks()` synchronously (used by at least `track-list`, `cover-grid`, `playlist-view`) will get `null` on first render and must handle a loading state that was previously invisible. + +**How to avoid:** +1. **Keep eager fetch for the initial view.** If the user's default view is "tracks," fetch tracks eagerly and lazy-load the rest. The library store already has the lazy `getTracks()` / `getAlbums()` pattern with `tracksLoading` / `albumsLoading` flags — the issue is that `eagerFetch()` triggers them all. +2. **Audit every `getCachedTracks()` / `getCachedAlbums()` call site.** Each one needs a loading state or skeleton UI. Don't change the store without updating all consumers. +3. **Measure before optimizing.** Profile the actual startup time with a large library. If `GetAllTracks()` takes 200ms for 50k tracks, that's fast enough to keep eager. The bottleneck might be rendering, not fetching. +4. **If lazy loading, implement skeleton/shimmer states** that feel faster than the current blank-then-populate pattern. The perceived performance matters more than actual latency. + +**Warning signs:** +- Empty track list visible for a fraction of a second on app start +- Cover grid shows placeholder then jumps as albums load +- Components flash between empty and populated states +- User says "it feels slower" even if total time is the same + +**Phase to address:** +Performance phase. Profile first, then decide whether lazy loading is actually needed. If yes, update all consumer components in the same change. + +--- + +### Pitfall 6: Queue Persistence Migration Loses Queue State + +**What goes wrong:** +You change queue persistence from full-rewrite (`DELETE + INSERT ALL`) to incremental (`INSERT/DELETE individual rows`). The schema or persistence format changes. The user restarts the app and their queue is empty because the new `RestoreState()` can't read the old format, or the migration from full-rewrite to incremental left the `queue_tracks` table in an inconsistent state (e.g., duplicate positions, missing foreign keys). + +**Why it happens:** +The current `persistTracks()` does `DELETE FROM queue_tracks` + batch INSERT inside a transaction. This is a clean slate every time — position values are always sequential and consistent. An incremental approach must maintain position ordering through individual INSERT/DELETE/UPDATE operations. If you change the persistence strategy without migrating existing data, or if the new code assumes positions are always contiguous when the old code may have left gaps, the restore fails. + +**How to avoid:** +1. **The new persistence code must be able to read the old format.** The `queue_tracks` table has `(id, audio_file_id, position)`. As long as you don't change the schema, `RestoreState()` works unchanged. Only change the write path. +2. **Write a test that persists with the old method, then restores with the new method.** This is the backward compatibility test. +3. **Keep the full-rewrite as a fallback** for `SetQueue` (which replaces the entire queue anyway). Only use incremental for `AddTrack`, `RemoveTrack`, and `MoveTrack`. +4. **Validate position ordering after every incremental mutation** in debug builds. Assert that positions are monotonically increasing. + +**Warning signs:** +- Queue is empty after app restart +- Queue tracks are in wrong order after restart +- `RestoreState` logs errors about missing audio files +- Queue tracks have duplicate or negative positions + +**Phase to address:** +Performance phase. Write queue persistence tests first, then change the write strategy. + +--- + +### Pitfall 7: Wails Binding Regeneration Silently Breaks Frontend After Go Struct Changes + +**What goes wrong:** +You rename a Go struct field (e.g., `queue.Track.Position` → `queue.Track.SortOrder`), change a method signature, or add a new exported method to a bound struct. The Wails binding generator creates new TypeScript files in `frontend/wailsjs/go/`, but the generated types don't match what the frontend code expects. The TypeScript compiler may or may not catch this depending on whether the frontend uses the generated types or inline types. If the frontend uses `any` casts or untyped event payloads, the mismatch is silent. + +**Why it happens:** +Wails v2 binding generation (`wails generate module`) creates TypeScript interfaces from Go structs. But the event payloads emitted via `runtime.EventsEmit()` are untyped — they're `any` on the TypeScript side. So if you change the shape of `queue.TracksModified` in Go, the `EventsOn` handler in `queue-store.ts` receives the new shape but TypeScript doesn't enforce it. The `applyTracksDelta` method accesses `.action`, `.tracks`, `.index`, `.positions` — if any of these rename, the delta application silently fails (produces `undefined`). + +**How to avoid:** +1. **After any Go struct change to a type used in events, grep the frontend for all usages of that type's fields.** Event payloads are the blind spot — Wails bindings don't cover them. +2. **Run `wails generate module` after every Go struct change** and check the git diff of the generated TypeScript files. If a field renamed, the diff will show it. +3. **Consider adding a shared event payload validation layer.** The `TracksModified` struct in Go and the `TracksModified` type in `queue-store.ts` must match — add a build step or test that verifies field parity. +4. **Never change JSON tags on event payload structs without updating the TypeScript counterpart.** The JSON tags (`json:"currentIndex"`) are what actually matters for the frontend, not the Go field names. + +**Warning signs:** +- Queue panel stops updating after a Go struct change +- Event handlers silently receive `undefined` for renamed fields +- `wails dev` works but production build has broken types +- Frontend TypeScript compiles but runtime behavior is wrong + +**Phase to address:** +Every phase that touches Go structs used in events. Add a validation check (build script or test) early. + +## Technical Debt Patterns + +| Shortcut | Immediate Benefit | Long-term Cost | When Acceptable | +|----------|-------------------|----------------|-----------------| +| Fixing race without test first | Faster to ship the fix | If fix introduces deadlock or regression, no test catches it. May need to fix again. | Only for trivial races like `SetContext` one-liners where the fix is mechanical (add lock around single assignment) | +| Using `:memory:` SQLite for all tests | Faster tests, no cleanup | Hides WAL behavior, FK enforcement, migration ordering issues | Acceptable for pure query logic tests. Never for integration or migration tests. | +| Keeping raw SQL for batch operations | Avoids sqlc limitations with dynamic IN clauses | Diverges from project's type-safe query pattern. No compile-time checking. | Acceptable when documented. sqlc's `sqlc.slice()` has limitations with SQLite that may not support the batch pattern. | +| Full queue rewrite on every mutation | Simple, always-consistent persistence | O(n) for every single add/remove. For 5000-track queues, this is noticeable. | Acceptable for SetQueue and RestoreState. Not acceptable for AddTrack/RemoveTrack hot paths. | +| Skipping player tests due to hardware | No CI flakiness from audio devices | Player regressions only caught manually. Volume math, state serialization, streamer chain setup are all untested. | Extract pure logic into testable functions. The actual speaker interaction can stay integration-only. | +| `startupErr` as package-level var | Simple error propagation between OnStartup and OnDomReady | Not thread-safe, not testable, global mutable state | Never — move to struct field. Low effort, high correctness gain. | + +## Integration Gotchas + +| Integration | Common Mistake | Correct Approach | +|-------------|----------------|------------------| +| beep speaker + Player mutex | Calling `speaker.Lock()` from a code path that already holds `p.mu` in a blocking manner, or removing the goroutine dispatch in the beep callback | Maintain strict ordering: `p.mu` before `speaker.Lock()`. Keep `go p.onPlaybackFinished()` as a goroutine dispatch. Never hold both locks when calling into queue. | +| Wails event system + TypeScript stores | Assuming event delivery order matches emission order. Wails events are async from Go → JS bridge. Two events emitted sequentially in Go may arrive in either order in TS. | Design stores to handle events in any order. Use full-state events (`QueueChanged`) as periodic correction. Don't rely on `QueueTracksModified` always arriving before `QueueIndexChanged`. | +| sqlc + FTS5 virtual tables | Expecting sqlc to generate queries against FTS5 `MATCH` syntax. sqlc's SQLite support doesn't fully understand FTS5 virtual table syntax. | Keep FTS5 queries as hand-crafted SQL. Only use sqlc for standard table queries. Document FTS queries as intentional exceptions to the sqlc pattern. | +| modernc.org/sqlite + PRAGMA | Assuming PRAGMAs persist across connections. With the pure-Go driver, each new connection (from the pool) starts fresh. `SetMaxOpenConns(1)` mitigates this but `foreign_keys` must still be set per connection. | Set `PRAGMA foreign_keys = ON` immediately after opening, as the codebase already does. For tests, replicate this in the test helper. | +| TOML config + new fields | Adding a new config section without a default. Existing users' TOML files don't have the new section. `toml.Decode` leaves it as `nil`. `applyDefaults()` runs after decode but only creates defaults for `nil` sections — doesn't fill in missing fields within existing sections. | Always add defaults in `applyDefaults()` for new fields. Test config loading with an empty file and a minimal file (only `[Library]` section). | +| Wails lifecycle + SetContext ordering | Calling `RestoreState()` before `SetContext()`. The restore tries to emit events but context is nil. Or calling `SetPlayer()` after `RestoreState()` — the restored queue tries to auto-advance but player reference is nil. | Follow the exact ordering in `OnStartup()`: SetContext → SetPlayer → RestoreState. Document this ordering requirement. Test with a mock that verifies call order. | + +## Performance Traps + +| Trap | Symptoms | Prevention | When It Breaks | +|------|----------|------------|----------------| +| Full queue persistence on every mutation | Slight lag when adding/removing single tracks. `commitMutation()` calls `persistTracks()` which does DELETE + INSERT ALL. | Profile `persistTracks()` for queue sizes of 100, 1000, 5000 tracks. Implement incremental persistence for single-track operations. | Queues > 1000 tracks with frequent mutations (drag-reorder, bulk add). ~50-100ms per operation at 5000 tracks with SQLite writes. | +| Eager full-library fetch on startup | Slow initial load for large libraries. Four simultaneous `GetAll*` queries each doing full table scans with JOINs. | Measure actual query times: if < 300ms for target library size, keep eager. If > 300ms, lazy-load non-default views. | Libraries > 50k tracks. Each `GetAllTracks` query with JOIN chain may take 500ms+. | +| FTS5 JOIN chain in every search query | Search latency scales with library size. The 5-table JOIN chain runs for every keystroke (debounced). | The JOIN chain is necessary for displaying results. Optimize by ensuring FTS5 index is populated correctly so `MATCH` reduces the result set before JOINs. Add `LIMIT` to all search queries. | Libraries > 100k tracks without proper FTS5 indexing. | +| Frontend re-renders on every store notification | Track list with 10k+ items re-renders when any store property changes. Virtual scrolling helps but the data array replacement triggers Lit's dirty check. | Use `===` reference equality checks. Only replace arrays when contents actually changed, not on every event. Lit's `@state()` triggers re-render on any assignment. | Track lists > 5000 items with frequent events (playback position updates). | +| SetQueue Phase 2 re-fetches all tracks | `resolveRemainingTracks` calls `lookupTrackMetaBatch(filePaths)` for ALL paths including those already resolved in Phase 1. | Pass Phase 1 results to Phase 2. Only look up the delta. For a 5000-track album, this saves ~50 lookups. | Large playlists/albums > 500 tracks where Phase 1's 50-track window is a small fraction. | + +## UX Pitfalls + +| Pitfall | User Impact | Better Approach | +|---------|-------------|-----------------| +| Introducing loading states where none existed | User who has been using the app daily suddenly sees spinners or empty states on startup. Perceives app as slower even if total time is the same. | Preserve instant-display for the default view. Only add loading states for lazily-loaded secondary views (artist detail, genre browsing). Use skeleton UIs, not spinners. | +| Fixing queue persistence timing | If incremental persistence introduces a delay between mutation and save, a crash between mutation and save loses the change. User adds 50 tracks, app crashes, queue is reverted. | Persist synchronously for user-initiated mutations (add, remove). Only defer persistence for background operations (Phase 2 resolve). | +| Changing search result ranking | Consolidating FTS5 queries might change which columns are weighted. User's muscle memory for search ("typing 'beat' always shows Beatles first") breaks silently. | Capture current search results for common queries before refactoring. Validate ranking stability after changes. | +| Config migration failures | User's config.toml has custom theme settings. A config change causes parse failure on startup. App doesn't start. User has no way to recover without deleting config. | Always handle TOML parse errors gracefully — log the error, use defaults, don't crash. The current code returns an error from `NewConfig()` which is fatal. Consider falling back to defaults with a warning. | +| Event ordering changes | Refactoring changes when events are emitted relative to state changes. Frontend shows stale data for a frame (queue shows old index while track changed). | Ensure state is consistent before emitting any events. Emit all related events together. Use the full-state `QueueChanged` event as the ground truth; deltas are optimizations. | + +## "Looks Done But Isn't" Checklist + +- [ ] **Queue tests:** Often missing concurrent SetQueue test — verify two rapid SetQueue calls don't corrupt state (generation counter works) +- [ ] **Search consolidation:** Often missing empty-string and special-character test cases for FTS5 — verify `"`, `*`, `(`, `)` in search queries don't crash +- [ ] **Config roundtrip:** Often missing test with unknown TOML keys — verify future config fields don't cause parse errors on older app versions +- [ ] **Migration tests:** Often missing test on existing database with data — verify migration doesn't drop existing rows +- [ ] **Incremental persistence:** Often missing test for queue order after remove-from-middle — verify remaining tracks keep correct positions +- [ ] **Lock ordering:** Often missing test for rapid LoadFile during playback — verify the beep callback + new LoadFile don't deadlock +- [ ] **Event parity:** Often missing validation that Go event constants match TypeScript — verify no typos exist between `events.go` and `events.ts` +- [ ] **Lazy loading:** Often missing test for component render with null data — verify all components handle loading state without errors +- [ ] **FTS rebuild:** Often missing test for `RebuildSearchIndex` idempotency — verify running it twice doesn't create duplicate index entries + +## Recovery Strategies + +| Pitfall | Recovery Cost | Recovery Steps | +|---------|---------------|----------------| +| Deadlock from lock ordering violation | LOW | Identify the two goroutines holding locks (SIGQUIT dump). Fix the ordering. Add a comment. The app just needs restart — no data loss. | +| Silent search regression from FTS consolidation | MEDIUM | Revert the consolidation. Write the tests that should have existed. Re-apply consolidation with tests passing. Data is intact — only query logic changed. | +| Queue state loss from persistence change | HIGH | If queue_tracks table was corrupted, user loses their queue. No automatic recovery. Prevention: always write persistence tests before changing the write path. Mitigation: keep a backup of queue state in a second table during migration period. | +| Config parse failure on startup | MEDIUM | App won't start. User must manually edit or delete config.toml. Prevention: handle TOML errors gracefully, fall back to defaults. Recovery: add a `--reset-config` CLI flag. | +| Frontend empty state regressions | LOW | Components show blank instead of data. Fix by adding null checks and loading states. No data loss. But user trust is eroded. | +| Wails binding mismatch after struct rename | MEDIUM | Frontend silently receives undefined fields. Fix by running `wails generate module` and updating TypeScript event handlers. No data loss but broken UI until fixed. | +| In-memory test false positive | HIGH (delayed) | Tests pass, bug ships. Discovered when user reports data loss or corruption in production. Prevention: use file-based SQLite in tests from the start. Recovery depends on which bug shipped. | + +## Pitfall-to-Phase Mapping + +| Pitfall | Prevention Phase | Verification | +|---------|------------------|--------------| +| Refactoring concurrency without tests | Testing infrastructure (first phase) | Queue characterization tests pass. `-race` flag clean on all test runs. | +| In-memory SQLite test divergence | Testing infrastructure (first phase) | `NewTestDB()` helper uses file-based SQLite with identical pragma setup. All DB tests use it. | +| Player deadlock from lock ordering | Player refactoring phase (after testing) | Pure logic extracted and tested. Lock-sensitive code unchanged or minimally changed with lock graph documented. No SIGQUIT needed. | +| FTS5 query consolidation breaks search | Database/code quality phase | Search tests capture before/after results for: full metadata track, metadata-less track, special characters, empty query. Zero-diff after consolidation. | +| Eager-to-lazy loading UX regression | Performance phase | Profile data establishes baseline. If lazy loading applied, all `getCached*()` call sites handle null. Skeleton UI visible for < 200ms. | +| Queue persistence state loss | Performance phase | Queue persistence roundtrip tests pass. Old-format → new-format compatibility test passes. Queue survives app restart in all modes. | +| Wails binding mismatch | Every phase (continuous) | `wails generate module` runs in CI or pre-commit. Event payload types have TypeScript interface definitions that match Go struct JSON tags. | +| Config migration failure | Correctness phase | Config roundtrip test with empty file, minimal file, and full file. Unknown keys don't crash. Missing sections get defaults. | +| Event ordering assumptions | Correctness/UX phase | Frontend stores handle events in any order. Full-state events correct drift.

It is organized by the five research questions, prioritized by impact. + +--- + +## 1. Go Concurrency Safety — Priority: CRITICAL + +**Confidence:** HIGH — based on Go standard library docs, race detector behavior, and codebase analysis. + +### The Core Problem + +YellowJacket has three documented data races, all following the same anti-pattern: a `SetContext()` method writes a struct field without holding the struct's mutex, while other methods read that field under the mutex. This is a textbook data race even if "it works in practice." + +### Pattern: Fix SetContext Races + +The `Queue.SetContext()`, `Library.SetContext()`, and `playlist.Service.SetContext()` all share the same bug. The fix is the same for all three: + +```go +// BEFORE (race): +func (q *Queue) SetContext(ctx context.Context) { + q.ctx = ctx // ← no lock, but q.ctx is read under q.mu elsewhere +} + +// AFTER (correct): +func (q *Queue) SetContext(ctx context.Context) { + q.mu.Lock() + defer q.mu.Unlock() + q.ctx = ctx +} +``` + +**Why this matters:** The Go race detector (`-race` flag) will flag this in tests. Since `make test` already runs with `-race`, any test that exercises `SetContext` alongside event emission will fail. Fixing these races unblocks writing tests for queue, library, and playlist packages. + +**Why not use `sync/atomic`:** `context.Context` is an interface (two words: type pointer + data pointer). `sync/atomic` only works on single-word types. Use the existing mutex. + +### Pattern: Player Double-Lock Fix + +The player's `SetContext` acquires and releases the mutex twice in succession: + +```go +// BEFORE (window between locks): +func (p *Player) SetContext(ctx context.Context) { + p.mu.Lock() + p.ctx = ctx + p.mu.Unlock() + + p.mu.Lock() + p.restoreStateLocked() + p.mu.Unlock() +} + +// AFTER (single acquisition): +func (p *Player) SetContext(ctx context.Context) { + p.mu.Lock() + defer p.mu.Unlock() + p.ctx = ctx + p.restoreStateLocked() +} +``` + +**Why:** Between the two lock acquisitions, another goroutine can modify state. The combined lock makes the set-context-and-restore atomic. + +### Pattern: Lock Ordering Documentation + +The player already documents its lock ordering rule: "acquire `p.mu` BEFORE `speaker.Lock()`." This is correct and critical. The `go p.onPlaybackFinished()` dispatch from the beep callback is essential — removing the goroutine dispatch would deadlock because the beep callback holds `speaker.Lock()` and `onPlaybackFinished` acquires `p.mu`. + +**Recommendation:** Add a `// Lock ordering:` comment block to the Queue and Library structs as well, even though they only have one lock each. Document what operations must NOT hold the lock (event emission, player callbacks). + +```go +// Queue manages an ordered list of tracks for playback. +// +// Concurrency: q.mu protects all mutable fields. Event emission +// (emitQueueChanged, etc.) is called WITH q.mu held because the +// Wails EventsEmit is non-blocking. The playbackFinishedHandler +// (auto-advance) re-enters the queue via AddTrack/Next, so it +// must NOT be called while holding q.mu. +type Queue struct { + mu sync.Mutex + // ... +} +``` + +### Testing Pattern: Race Detector as Test Oracle + +```bash +# Already in Makefile — verify this is the exact command: +make test # → go test -tags webkit2_41 -race -count=1 -timeout 120s ./... +``` + +The race detector is the most valuable tool here. Every new test implicitly checks for races when run with `-race`. No additional tooling needed — just write tests that exercise concurrent paths: + +```go +func TestQueueSetContextRace(t *testing.T) { + q := NewQueue(slog.Default(), testDB) + + // Simulate Wails calling SetContext while queue operations run. + var wg sync.WaitGroup + wg.Add(2) + go func() { + defer wg.Done() + q.SetContext(context.Background()) + }() + go func() { + defer wg.Done() + q.GetState() // reads under lock + }() + wg.Wait() +} +``` + +### What NOT to Do + +| Anti-Pattern | Why It's Wrong | Instead | +|---|---|---| +| `sync.RWMutex` for Queue/Player | These structs have frequent writes AND reads from multiple goroutines on the same timeline. RWMutex only helps when reads vastly outnumber writes and are long-running. Desktop event-driven access patterns don't benefit. | Keep `sync.Mutex`. Simpler, fewer bugs. | +| Channel-based state management | Replacing mutexes with channels for Queue state would require rewriting all methods. The current mutex pattern is correct, just under-applied. | Fix the races by adding lock acquisitions to SetContext methods. | +| `sync.Map` for entityCache | `sync.Map` is optimized for concurrent reads from many goroutines. The entityCache is accessed from a single DB-writer goroutine. It would add overhead with zero benefit. | Keep plain maps (already correct). | +| Package-level mutex for startupErr | A package-level mutex is worse than the disease. | Move `startupErr` to a field on `YellowJacketApp` struct. | + +--- + +## 2. SQLite WAL Mode Optimization — Priority: HIGH + +**Confidence:** HIGH — based on SQLite official docs (sqlite.org/wal.html), modernc.org/sqlite driver docs, and codebase analysis. + +### Current Setup Analysis + +The database initialization is solid: +- WAL mode via `?_journal_mode=WAL` in DSN (**correct**) +- `_busy_timeout=5000` — 5 second busy wait (**correct**, prevents SQLITE_BUSY in most cases) +- `SetMaxOpenConns(1)` — single writer (**correct**, required for pure-Go driver) +- `PRAGMA foreign_keys = ON` (**correct**) + +### Missing PRAGMAs to Add + +```go +// Add after foreign_keys pragma in NewDB(): +pragmas := []string{ + "PRAGMA foreign_keys = ON", + "PRAGMA synchronous = NORMAL", // WAL-safe, much faster + "PRAGMA cache_size = -8000", // 8MB page cache (default is -2000 = 2MB) + "PRAGMA mmap_size = 67108864", // 64MB memory-mapped I/O + "PRAGMA temp_store = MEMORY", // Temp tables in memory + "PRAGMA optimize", // Run at connection open +} +``` + +**Why `synchronous = NORMAL`:** In WAL mode, NORMAL provides durability against process crashes (only power loss can cause data loss of the last transaction). FULL is the default and fsyncs the WAL on every commit, which is unnecessary for a desktop music player where the data can be rescanned from disk. + +**Why `cache_size = -8000`:** The negative value means 8000 KiB (8MB). The default 2MB is fine for small databases but YellowJacket libraries can have 50k+ tracks. Larger cache reduces disk I/O for repeated queries (all-tracks, search, queue operations). + +**Why `mmap_size`:** Memory-mapped I/O lets SQLite read pages directly from the OS page cache. 64MB covers most music library databases entirely. With modernc.org/sqlite (pure Go), mmap is handled by the underlying C translation and works on Linux/macOS/Windows. + +**Why `PRAGMA optimize` at open:** Runs `ANALYZE` on tables where the optimizer thinks statistics are stale. Zero cost if stats are fresh. + +### Add `PRAGMA optimize` at Shutdown + +```go +// In app.go OnShutdown: +func (a *YellowJacketApp) OnShutdown(ctx context.Context) { + // ... existing cleanup ... + _, _ = a.db.ExecContext("PRAGMA optimize") // Update query planner stats +} +``` + +SQLite docs recommend running `PRAGMA optimize` at close to ensure statistics are written for the next session. + +### Query Consolidation: FTS5 JOIN Deduplication + +The codebase has 5 copies of the same FTS5 JOIN pattern. Extract it: + +```go +// backend/database/search.go + +// ftsMetadataJoin is the common JOIN clause for resolving audio file +// metadata through the recording → artist_credit → release_group chain. +// Use with "FROM search_index si" or "FROM audio_files af" as the base. +const ftsMetadataJoin = ` + JOIN audio_files af ON af.id = si.rowid + LEFT JOIN recordings r ON af.recording_id = r.id + LEFT JOIN artist_credit ac ON r.artist_credit_id = ac.id + LEFT JOIN ( + SELECT recording_id, + MIN(release_group_id) AS release_group_id + FROM release_group_recordings + GROUP BY recording_id + ) rgr ON r.id = rgr.recording_id + LEFT JOIN release_groups rg ON rgr.release_group_id = rg.id +` +``` + +Then each search function references the constant instead of duplicating the SQL. This ensures schema changes only need one update. + +**Alternative:** Move these to sqlc queries where possible. The `SearchFTS` and `SearchFTSByFilename` functions can't easily use sqlc because the FTS5 `MATCH` syntax isn't well-supported by sqlc's parser. Keep them as hand-crafted SQL with the shared constant. Document why with a comment. + +### Queue Persistence: Incremental Updates + +The current `persistTracks()` does `DELETE ALL + INSERT ALL` on every mutation. For a queue with 1000 tracks, every add/remove/move rewrites all 1000 rows. + +**Pattern: Differential persistence for single-track operations:** + +```go +// For AddTrack — single INSERT instead of full rewrite: +func (q *Queue) persistAddTrack(track Track) { + err := q.db.Queries.InsertQueueTrack(q.db.Ctx, sqlcgen.InsertQueueTrackParams{ + AudioFileID: track.AudioFileID, + Position: track.Position, + }) + if err != nil { + q.logger.Error("Failed to persist added track", "err", err) + } +} + +// For RemoveTrack — single DELETE: +func (q *Queue) persistRemoveTrack(position int64) { + err := q.db.Queries.DeleteQueueTrackByPosition(q.db.Ctx, position) + if err != nil { + q.logger.Error("Failed to persist removed track", "err", err) + } +} +``` + +**Keep full rewrite for:** `SetQueue`, `RestoreState`, shuffle reordering — cases where the entire queue changes at once. + +**Estimated impact:** Reduces O(n) per-mutation writes to O(1) for the common case (add/remove single track). For a 5000-track queue, this eliminates ~10,000 unnecessary row writes per track operation. + +### What NOT to Do + +| Anti-Pattern | Why It's Wrong | Instead | +|---|---|---| +| Connection pooling (`SetMaxOpenConns > 1`) | modernc.org/sqlite is a single-writer database. Multiple connections cause SQLITE_BUSY errors. The current `SetMaxOpenConns(1)` is correct. | Keep `SetMaxOpenConns(1)`. | +| `_txlock=immediate` on all transactions | Immediate locking blocks all readers during writes. The default deferred locking only acquires a write lock when needed. For a desktop app with infrequent writes, deferred is fine. | Use immediate locking ONLY for critical write transactions (queue persistence) where you want to fail fast on contention. | +| Switching to `mattn/go-sqlite3` (CGo) | Adds CGo dependency, complicates cross-compilation, and the project constraint explicitly prohibits it. modernc.org/sqlite v1.45+ performance is within 10-20% of CGo for most workloads. | Stay on modernc.org/sqlite. | +| WAL2 mode | WAL2 is experimental in SQLite. Not available through any Go driver. | Stay on standard WAL. | + +--- + +## 3. Lit Web Component Performance — Priority: MEDIUM + +**Confidence:** MEDIUM — based on Lit official docs and @lit-labs/virtualizer usage in the codebase. + +### Current State + +The codebase already uses `@lit-labs/virtualizer` v2.1.1 in all list views (track-list, cover-grid, artists-view, genres-view, queue-panel). The virtualizer handles DOM recycling for large datasets. The main performance concerns are: + +1. **Eager full-library fetch on startup** — `libraryStore.eagerFetch()` loads all tracks, albums, artists, genres simultaneously +2. **Large component files** — 1400-2600 lines mixing concerns (though this is a code quality issue, not a performance issue per se) +3. **Rendering cost of metadata-heavy rows** — each track row has 16+ fields + +### Pattern: Lazy Loading Per View + +Replace `eagerFetch()` with on-demand loading: + +```typescript +class LibraryStore { + // Instead of fetching all four collections at construction: + constructor() { + EventsOn(Events.LibraryScanComplete, () => { + this.invalidate(); + }); + this.loadCoverSize(); + // Remove: this.eagerFetch(); + } + + // The existing getTracks/getAlbums already support lazy loading — + // they check for null and fetch if needed. The only change needed + // is removing eagerFetch() from the constructor. +} +``` + +**Why:** The existing `getTracks()`, `getAlbums()`, etc. already have null-check-and-fetch logic. The `eagerFetch()` in the constructor defeats this by loading everything upfront. Removing it means only the active view's data is fetched when first navigated to. + +**Risk:** First navigation to each view will have a brief loading delay. Mitigate with loading indicators (the `tracksLoading`/`albumsLoading` flags already exist). + +### Pattern: Minimize Re-renders with `guard` Directive + +For expensive computed values in templates (like filtered/sorted track lists), use Lit's `guard` directive to avoid recomputation: + +```typescript +import { guard } from 'lit/directives/guard.js'; + +// In render(): +${guard([this.tracks, this.sortColumn, this.sortDirection], () => + this.sortedTracks() +)} +``` + +**When to use:** For any computed property that depends on reactive properties but is expensive to compute (sorting 50k tracks, filtering, etc.). + +### Pattern: keyed Rendering for Virtualizer Lists + +Ensure virtualizer items have stable keys so DOM nodes are reused correctly when the list changes: + +```typescript +// The virtualizer uses index-based identity by default. +// For track lists that can be reordered (queue, playlists), +// provide a keyFunction: + track.filePath} + .renderItem=${(track: Track) => html`...`} +> +``` + +**Why:** Without stable keys, reordering a list causes the virtualizer to re-render every visible row. With keys, it reuses existing DOM nodes for rows that moved position. + +### What NOT to Do + +| Anti-Pattern | Why It's Wrong | Instead | +|---|---|---| +| Moving to React/Preact | The project uses Lit Web Components with Wails' WebView. Switching frameworks is explicitly out of scope and would require rewriting all 20+ components. | Stay on Lit 3.x. | +| Pre-rendering / SSR | Desktop app. No server. No need. | N/A | +| Replacing `@lit-labs/virtualizer` with a custom solution | The virtualizer is battle-tested and integrates with Lit's update lifecycle. A custom solution would need to handle the same edge cases (resize, scroll restoration, dynamic heights). | Keep `@lit-labs/virtualizer`. File bugs if issues are found. | +| `requestAnimationFrame` batching for store updates | Lit already batches updates at microtask timing. Adding rAF batching would add latency without benefit. | Let Lit handle batching. | + +--- + +## 4. Go Testing Strategies — Priority: HIGH + +**Confidence:** HIGH — based on Go standard library patterns and codebase-specific analysis. + +### Strategy: In-Memory SQLite for Database Tests + +modernc.org/sqlite supports in-memory databases. Use them for fast, isolated tests: + +```go +// backend/database/testhelper_test.go (shared across test files in the package) + +func newTestDB(t *testing.T) *database.DB { + t.Helper() + // Use ":memory:" with shared cache so the connection sees the same DB. + // The query string params mirror production config. + db, err := database.NewTestDB(":memory:?_journal_mode=WAL&_busy_timeout=5000") + if err != nil { + t.Fatal(err) + } + t.Cleanup(func() { db.Close() }) + return db +} +``` + +**For this to work, add a `NewTestDB` constructor to the database package** that accepts a custom DSN instead of computing one from the user data directory: + +```go +// backend/database/database.go + +// NewTestDB creates a database connection with a caller-provided DSN. +// Intended for unit tests that use in-memory databases. +func NewTestDB(dsn string) (*DB, error) { + // Same initialization logic as NewDB but with custom DSN. + // Runs migrations, sets pragmas, etc. +} +``` + +**Why in-memory:** Tests run in ~1ms instead of ~50ms. No filesystem cleanup. No conflict between parallel tests. Each test gets a fresh database. + +**Important:** SQLite in-memory databases with `SetMaxOpenConns(1)` work correctly — the single connection sees a consistent view. No need for shared cache mode with a single connection. + +### Strategy: Extract Pure Functions from Player + +The player has testable logic that doesn't need audio hardware: + +```go +// Volume math — currently inline in player methods: +func userVolumeToBeep(userVolume int) (volume float64, silent bool) { + if userVolume <= 0 { + return 0, true + } + // Convert 0-100 linear user volume to beep's logarithmic Volume field. + // Base is 2, so Volume = log2(userVolume/MaxUserVol * range) + // This is the math currently embedded in Set/GetVolume methods. + return math.Log2(float64(userVolume) / float64(MaxUserVol)), false +} + +// State serialization — currently inline in persist/restore: +func serializePlayerState(state State, volume int, filePath string) PlayerStateRow { ... } +func deserializePlayerState(row PlayerStateRow) (State, int, string) { ... } +``` + +**Why:** These pure functions can be tested exhaustively (edge cases: volume 0, volume 100, max uint64 trackChangeID, empty filepath) without any speaker initialization or Wails context. + +### Strategy: Interface-Based Mocking for Queue Tests + +The `Queue` depends on `TrackLoader` (player) and `*database.DB`. The `TrackLoader` is already an interface — perfect for testing: + +```go +// backend/queue/queue_test.go + +type mockPlayer struct { + loaded []string + playing bool + position int +} + +func (m *mockPlayer) LoadFile(path string) error { + m.loaded = append(m.loaded, path) + return nil +} +func (m *mockPlayer) Play() error { m.playing = true; return nil } +func (m *mockPlayer) IsPlaying() bool { return m.playing } +func (m *mockPlayer) CurrentPositionSeconds() (int, error) { return m.position, nil } +func (m *mockPlayer) UnloadTrack() { m.playing = false } + +func TestSetQueuePlaysFirstTrack(t *testing.T) { + db := newTestDB(t) + // Seed test tracks into db... + + q := queue.NewQueue(slog.Default(), db) + player := &mockPlayer{} + q.SetPlayer(player) + q.SetContext(context.Background()) + + q.SetQueue([]string{"/music/a.mp3", "/music/b.mp3"}, 0, false) + + if len(player.loaded) == 0 { + t.Fatal("expected player to load a file") + } + if player.loaded[0] != "/music/a.mp3" { + t.Errorf("expected first track, got %s", player.loaded[0]) + } +} +``` + +### Strategy: Config Round-Trip Testing + +```go +func TestConfigRoundTrip(t *testing.T) { + dir := t.TempDir() + path := filepath.Join(dir, "config.toml") + + original := config.DefaultConfig() + original.Theme.AccentColor = "#ff0000" + + err := config.Save(path, original) + if err != nil { + t.Fatal(err) + } + + loaded, err := config.Load(path) + if err != nil { + t.Fatal(err) + } + + if loaded.Theme.AccentColor != "#ff0000" { + t.Errorf("accent color not preserved: got %s", loaded.Theme.AccentColor) + } +} +``` + +### Strategy: Event Name Parity Validation + +Build-time check that Go and TypeScript event names match: + +```go +// backend/events/events_test.go + +func TestEventNameParity(t *testing.T) { + // Read the Go events constants via reflection or by parsing the source. + // Read frontend/src/events.ts. + // Compare the sets. + + goEvents := extractGoEventNames(t) // parse events.go + tsEvents := extractTSEventNames(t) // parse events.ts + + for name := range goEvents { + if _, ok := tsEvents[name]; !ok { + t.Errorf("Go event %q not found in TypeScript events.ts", name) + } + } + for name := range tsEvents { + if _, ok := goEvents[name]; !ok { + t.Errorf("TypeScript event %q not found in Go events.go", name) + } + } +} +``` + +**Implementation note:** Parse events.go for `const ( ... )` block string values. Parse events.ts for the `Events` object literal values. This is a ~50-line test that prevents silent event name drift forever. + +### Test Priority Order + +| Package | Why First | Test Count Estimate | +|---|---|---| +| `queue` | Central to playback, most concurrency issues, persistence bugs | ~15-20 tests | +| `database` | FTS5 edge cases, migration correctness, search behavior | ~10-15 tests | +| `config` | Round-trip fidelity, defaults, validation, permissions | ~8-10 tests | +| `player` (pure logic only) | Volume math, state serialization | ~5-8 tests | +| `events` | Parity check | 1 test | +| `library` | Scan logic is complex but depends on filesystem fixtures | ~10 tests (lower priority) | + +### What NOT to Do + +| Anti-Pattern | Why It's Wrong | Instead | +|---|---|---| +| Test doubles for SQLite (full mock DB layer) | In-memory SQLite IS the test double. It runs the same SQL engine with the same behavior. Mocking at the `*sql.DB` level loses all SQL correctness checking. | Use `:memory:` SQLite databases. | +| `testify` or other assertion libraries | The project uses standard `testing` only. Adding assertion libraries creates style inconsistency and dependency bloat. | Use `t.Errorf`, `t.Fatal`, and `if` checks. | +| Integration tests in CI for player | The player requires an audio output device. CI runners don't have one. The existing skip mechanism (`YELLOWJACKET_INTEGRATION`) is correct. | Extract pure functions from player; leave hardware tests as opt-in integration tests. | +| Coverage targets | The PROJECT.md explicitly says "Tests support refactoring, not standalone goal." Coverage targets incentivize low-value tests. | Test critical paths: queue operations, search, config round-trip, event parity. | + +--- + +## 5. beep/v2 Audio Library Patterns — Priority: MEDIUM + +**Confidence:** MEDIUM — based on beep wiki docs, gopxl/beep v2 API, and codebase lock ordering analysis. + +### Lock Ordering: The One Rule + +beep/v2 has a global speaker lock (`speaker.Lock()/speaker.Unlock()`). The player has its own `sync.Mutex`. The existing documented rule is correct: + +> **Always acquire `p.mu` BEFORE `speaker.Lock()`.** + +The critical implementation detail: the beep callback (end-of-track) runs with `speaker.Lock()` held. The player dispatches to a goroutine (`go p.onPlaybackFinished()`) so that it can safely acquire `p.mu`. **This goroutine dispatch MUST NOT be removed.** Removing it causes deadlock: + +``` +Deadlock scenario without goroutine dispatch: +1. beep callback fires (speaker lock HELD) +2. onPlaybackFinished tries to acquire p.mu → blocks if another goroutine holds p.mu +3. That other goroutine calls speaker.Lock() → blocks because speaker lock is held by beep +4. DEADLOCK +``` + +### Pattern: Speaker Lock Scope Minimization + +The current code correctly locks the speaker only when mutating streamer state: + +```go +func (p *Player) startPaused() { + speaker.Lock() + p.control.Paused = true + speaker.Unlock() + // speaker.Play registers streamers — does its own locking. + speaker.Play(beep.Seq(p.speakerStreamer, beep.Callback(func() { + go p.onPlaybackFinished() + }))) + p.state = Paused +} +``` + +**Keep speaker.Lock() regions as small as possible.** Never do I/O, logging, or event emission while holding the speaker lock. + +### Pattern: Streamer Chain Lifecycle + +The current `updateStreamers()` method correctly rebuilds the entire chain (base → resample → ctrl → volume) on each track load. This is the right pattern for beep — streamer chains are cheap to construct and shouldn't be reused across tracks. + +**One improvement:** The `updateStreamers` method preserves volume state across track changes, which is correct. But it could also preserve the paused state: + +```go +func (p *Player) updateStreamers(newBaseStreamer beep.StreamSeeker, sr beep.SampleRate) error { + // ...existing code... + + // Preserve existing pause state across track changes. + prevPaused := false + if p.control != nil { + prevPaused = p.control.Paused + } + + p.control = &beep.Ctrl{Streamer: p.resampled, Paused: prevPaused} + // ... +} +``` + +### Extractable Pure Logic from Player + +These functions can be extracted and tested without audio hardware: + +| Function | Current Location | Pure? | Test Value | +|---|---|---|---| +| Volume conversion (user 0-100 ↔ beep logarithmic) | Inline in `SetVolume`/`GetVolume` | Yes | Edge cases: 0, 1, 50, 100 | +| Display position calculation | `displayPositionSecsLocked()` | Yes (math only) | Seek position rounding, track length boundary | +| Track info construction | `getCurrentTrackInfoLocked()` | Mostly (reads state) | Null file, missing metadata | +| Resample quality mapping | Currently hardcoded `4` | Yes (when made configurable) | Quality 1-6 range validation | + +### What NOT to Do + +| Anti-Pattern | Why It's Wrong | Instead | +|---|---|---| +| Replacing beep with a lower-level audio library (oto, portaudio) | beep provides the streamer composition model (Seq, Ctrl, Volume, Resample) that the player relies on. Dropping to oto means reimplementing all of this. | Stay on beep/v2. File issues for bugs. | +| Multiple speaker.Init calls | `speaker.Init` can only be called once (or after `speaker.Close()`). Calling it again is undefined behavior. The current "init once on startup" is correct. | Keep single Init on startup. If sample rate needs to change, the entire speaker must be closed and reinitialized. | +| Holding p.mu during speaker.Play() | `speaker.Play()` does its own internal locking. Holding p.mu during the call is safe but unnecessary — and if beep ever calls back synchronously (which it currently doesn't for `Play()`), could cause issues. | Release p.mu before speaker.Play() if possible, or document why it's held. | + +--- + +## Development Tools: Existing Stack Assessment + +### Already Correct — No Changes Needed + +| Tool | Version | Assessment | +|---|---|---| +| golangci-lint v2 | v2.9.0 | Strict config already in place.

The consolidation milestone is not about new features — it's about making the existing codebase reliable, testable, and performant. The existing stack (Go 1.25, modernc.org/sqlite, beep/v2, Lit 3, sqlc) is correct and should not change. The work is purely internal quality improvement. + +The recommended approach is **tests-first, then refactoring**. The research consistently shows that every optimization and consolidation change (FTS5 query deduplication, queue incremental persistence, lazy library loading) is risky without tests to verify behavior is preserved. The critical dependency chain is: fix concurrency bugs → build test infrastructure → write tests → refactor safely. This ordering emerges independently from all four research files — STACK recommends in-memory SQLite testing, FEATURES shows test infrastructure as the top enabler, ARCHITECTURE proposes the same phase ordering, and PITFALLS warns that every refactoring without tests creates invisible regressions. + +The key risks are: (1) deadlock from player mutex + speaker lock ordering violations during refactoring, (2) FTS5 query consolidation silently changing search ranking, and (3) queue persistence migration losing queue state on restart. All three are mitigated by the same strategy: write characterization tests before changing the code. The player's lock ordering (`p.mu` before `speaker.Lock()`, goroutine dispatch in beep callback) is the one area requiring extreme caution — the recommendation is to extract pure testable logic and leave lock-sensitive paths alone unless absolutely necessary. + +## Key Findings + +### Recommended Stack + +The existing stack is correct.

The consolidation work is about fixing correctness issues within the existing patterns and adding test infrastructure. See [ARCHITECTURE.md](./ARCHITECTURE.md) for full details. + +**Six issues identified, in dependency order:** +1. **SetContext race fixes** — Add mutex guards to Queue, Library, Playlist `SetContext()`. Combine Player's double-lock into single acquisition. Move `startupErr` to struct field. +2. **Event name codegen** — Generate `frontend/src/events.ts` from `backend/events/events.go` using `go/ast`. Wire into `go generate` + pre-commit hook. +3. **Library store lazy loading** — Remove `eagerFetch()` from constructor. Lazy infrastructure already exists. Optional: paginated data providers for 100k+ libraries. +4. **Queue incremental persistence** — Use existing sqlc queries (`InsertQueueTrack`, `RemoveQueueTrackByPosition`, etc.) for single-track operations. Keep full rewrite for `SetQueue`/`Clear`. +5. **FTS5 query consolidation** — Create SQLite VIEW `track_metadata` encapsulating the 5-table JOIN. Migrate search queries to use VIEW. Keep inline JOINs in migrations. +6. **Test architecture** — `database.NewTestDB()` for in-memory SQLite. `internal/testdb` helper package. Mock only narrow interfaces (`TrackLoader`). Use `context.Background()` for Wails context in tests. + +### Critical Pitfalls + +Top 5 from [PITFALLS.md](./PITFALLS.md), ordered by severity: + +1. **Refactoring concurrency without tests creates invisible regressions** — Write characterization tests BEFORE fixing races. Fix `SetContext` first (lowest risk), Player last (most complex). The race detector is the oracle. +2. **Player deadlock from mutex + speaker lock ordering violation** — NEVER remove the `go p.onPlaybackFinished()` goroutine dispatch. NEVER refactor player lock code without drawing the full lock acquisition graph. Extract pure logic; leave lock-sensitive paths alone. +3. **FTS5 query consolidation breaks search ranking** — Write search tests BEFORE consolidating. Consolidate the JOIN clause only, not full queries. Verify `COALESCE` behavior is identical across all copies. +4. **Queue persistence migration loses queue state** — New persistence code must read old format. Test old-write → new-read compatibility. Keep full rewrite as fallback for complex operations. +5. **SQLite in-memory tests behave differently from file-based production** — Test helper must mirror production `NewDB()` exactly: same PRAGMAs, same migration sequence, `PRAGMA foreign_keys = ON`. Use `t.TempDir()` for file-based tests when WAL behavior matters. + +## Implications for Roadmap + +Based on dependency analysis across all four research files, with convergent recommendations: + +### Phase 1: Correctness Fixes & Test Foundation + +**Rationale:** Every other phase depends on either the concurrency fixes (to unblock `-race`-clean tests) or the test infrastructure (to safely refactor). This is the critical enabler. All four research files independently recommend this as the first step. + +**Delivers:** Race-free `SetContext` in all packages, `startupErr` moved to struct, config permissions fixed, swallowed errors surfaced, in-memory SQLite test helper, event name codegen, extracted testable player logic. + +**Features addressed:** All "Must fix" table stakes items + test infrastructure. + +**Pitfalls avoided:** Pitfall 1 (concurrency without tests), Pitfall 2 (in-memory test divergence), Pitfall 5 (config migration failures via roundtrip test). + +**Estimated items:** ~10 discrete changes, all LOW-MEDIUM effort individually. + +### Phase 2: Core Test Suite + +**Rationale:** With concurrency fixed and test infrastructure in place, write the safety net that protects all subsequent refactoring. Tests target the code AS IT IS (characterization tests), not as it will be after optimization. + +**Delivers:** Queue unit tests (~15-20), database/search tests (~10-15), config roundtrip tests (~8-10), player pure logic tests (~5-8), event parity test (1). Approximately 40-55 tests total. + +**Features addressed:** All test coverage items from FEATURES.md. + +**Pitfalls avoided:** Pitfall 1 (provides the safety net), Pitfall 4 (search tests before consolidation), Pitfall 6 (queue persistence tests before optimization). + +**Estimated effort:** HIGH — this is the largest phase by work volume, but it's the foundation for everything else. + +### Phase 3: SQL & Performance Optimization + +**Rationale:** With tests as a safety net, refactor the SQL layer and persistence. Schema changes (VIEW creation) should precede query pattern changes. Queue persistence optimization uses existing but unwired sqlc queries. + +**Delivers:** Deduplicated FTS5 queries via SQLite VIEW, incremental queue persistence for add/remove operations, SetQueue Phase 2 redundant lookup fix, scan warnings separated from fatal errors. + +**Features addressed:** FTS5 consolidation, queue persistence optimization, SetQueue Phase 2 fix, scan error separation. + +**Pitfalls avoided:** Pitfall 3 (FTS5 consolidation verified by Phase 2 tests), Pitfall 6 (queue persistence verified by Phase 2 tests). + +**Estimated effort:** MEDIUM — changes are well-scoped and verified by existing tests. + +### Phase 4: Frontend Performance & Polish + +**Rationale:** Frontend changes are independent of backend refactoring and lowest risk. The library store lazy loading is nearly zero-effort (removing code, not adding it). UI polish is last because it's the lowest priority for a consolidation milestone. + +**Delivers:** Lazy library loading (remove `eagerFetch()`), optimized re-renders with `repeat()` directive and stable keys, documentation of intentional exceptions (hand-crafted SQL, singleton store lifecycle). + +**Features addressed:** Library store lazy loading, frontend rendering optimization, documentation. + +**Pitfalls avoided:** Pitfall 5 (eager-to-lazy UX regression — mitigate by keeping eager for default view, audit all `getCached*` call sites). + +**Estimated effort:** LOW-MEDIUM — mostly removing code and CSS changes. + +### Phase Ordering Rationale + +- **Phase 1 → Phase 2:** You cannot write `-race`-clean tests without fixing the SetContext races first. Test infrastructure (`NewTestDB`) must exist before any DB-dependent tests. +- **Phase 2 → Phase 3:** Refactoring SQL and persistence without tests is the #1 pitfall identified by research. The tests characterize current behavior, then the refactoring is verified against them. +- **Phase 3 → Phase 4:** Frontend changes don't depend on backend refactoring, but doing them last means the backend API is stable. The SQLite VIEW from Phase 3 doesn't affect the frontend. +- **Within Phase 1:** SetContext fixes → test helper → event codegen (independent items, can be parallelized). +- **Within Phase 3:** SQL VIEW creation → query migration → queue persistence (schema before queries before consumers). + +### Research Flags + +Phases likely needing deeper research during planning: +- **Phase 2 (Core Test Suite):** The queue test architecture needs careful design — mock player interface, test data seeding patterns, event verification strategy. `/gsd-research-phase` recommended for the queue test design. +- **Phase 3 (SQL Optimization):** sqlc's handling of SQLite VIEWs with FTS5 virtual tables needs validation. The VIEW concept is sound but edge cases in sqlc's SQLite parser are unknown. Quick validation needed before committing to VIEW approach. + +Phases with standard patterns (skip research-phase): +- **Phase 1 (Correctness Fixes):** All fixes are mechanical (add lock, move field, fix permissions). Well-documented Go patterns. +- **Phase 4 (Frontend):** Removing `eagerFetch()` is a one-line change. Lit `repeat()` directive is well-documented. + +## Confidence Assessment + +| Area | Confidence | Notes | +|------|------------|-------| +| Stack | HIGH | All recommendations come from official docs (SQLite, Go stdlib, Lit, beep).

MPRIS lifecycle callback errors (Pause, Seek) appear in the application log instead of being silently discarded + 4. Artist credit link creation checks the actual error — only UNIQUE constraint violations are ignored, all other errors are surfaced + 5.

A code generator reads Go event constants from `backend/events/events.go` and produces `frontend/src/events.ts`, wired into `go generate` and the pre-commit hook — adding an event in Go without regenerating TypeScript fails the hook + 3. Queue batch lookups in `persistence.go` use `sqlc.slice()` for IN clauses where sqlc supports it, replacing `fmt.Sprintf` placeholder construction + 4.

When "Add" is clicked: + - Push `duplicates[currentIndex].FilePath` to `tracksToAdd`. + - If `applyToAll` is true: push ALL remaining duplicate file paths to `tracksToAdd`, then finalize. + - Else: advance `currentIndex`. If past end, finalize. +3. When "Skip" is clicked: + - Do NOT add the current track. + - If `applyToAll` is true: skip all remaining (finalize immediately). + - Else: advance `currentIndex`. If past end, finalize. +4. `finalize()`: + - Combine `uniquePaths` + `tracksToAdd` into one array. + - If array is non-empty, call `await AddTracksToPlaylist(this.playlistId, combined)`. + - Dispatch `playlist-action-complete` event (bubbles: true, composed: true). + - Close dialog. + +**Styling:** Follow project conventions — use `--yj-*` CSS custom properties. Match the `track-details.ts` dialog styling for consistency (same `wa-dialog::part(*)` rules). The track card should have a subtle background (`--yj-bg-elevated`), rounded corners (6px), padding (16px), and the info stacked vertically. + +Use `formatMilliseconds` from `@utils/time` for duration display. + +**Important:** The wa-switch `@wa-change` event fires with `e.target.checked` as a boolean. Use: +```html + { + this.applyToAll = (e.target as HTMLInputElement).checked; + }} +> + Apply to all remaining + +``` + + + `npm run build` (or the project's build command) compiles without errors.

Add imports: +```typescript +import { + GetAllPlaylists, + AddTracksToPlaylist, + CreatePlaylistWithTracks, + FindDuplicateTracksInPlaylist, +} from '@go/playlist/Service'; +import '@components/duplicate-tracks-dialog/duplicate-tracks-dialog.js'; +import type { DuplicateTracksDialog } from '@components/duplicate-tracks-dialog/duplicate-tracks-dialog.js'; +``` + +2. Add a query for the dialog (render it in the template): +```typescript +@query('duplicate-tracks-dialog') +private duplicateDialog!: DuplicateTracksDialog; +``` + +3. Modify `handleSelectPlaylist` to check for duplicates BEFORE adding: +```typescript +private handleSelectPlaylist = async (playlistId: number) => { + if (this.loading || this.filePaths.length === 0) return; + this.loading = true; + + try { + const result = await FindDuplicateTracksInPlaylist(playlistId, this.filePaths); + const duplicates = result.Duplicates ?? []; + const unique = result.Unique ?? []; + + if (duplicates.length > 0) { + // Show dialog — it will handle adding tracks and dispatching completion + this.loading = false; + await this.updateComplete; + this.duplicateDialog.show(playlistId, duplicates, unique); + return; + } + + // No duplicates — add all directly + await AddTracksToPlaylist(playlistId, this.filePaths); + this.dispatchComplete(); + } catch (err) { + console.error('Failed to add tracks to playlist:', err); + } finally { + this.loading = false; + } +}; +``` + +4. Add the dialog element to the render template, just before the closing of `renderPlaylistList()` and `renderCreateForm()` — or better, add it to the main `render()` method so it's always in the DOM: +```typescript +override render() { + return html` + ${this.mode === 'create' ? this.renderCreateForm() : this.renderPlaylistList()} + + `; +} +``` + +Note: The `dispatchComplete` call from the dialog will bubble up through the playlist-picker, which is exactly what consumers listen for. The dialog's `playlist-action-complete` event is caught here and re-dispatched by the picker's own `dispatchComplete`. + +**playlist-view.ts changes:** + +1. Add imports at top (near existing imports): +```typescript +import { FindDuplicateTracksInPlaylist } from '@go/playlist/Service'; +import '@components/duplicate-tracks-dialog/duplicate-tracks-dialog.js'; +import type { DuplicateTracksDialog } from '@components/duplicate-tracks-dialog/duplicate-tracks-dialog.js'; +``` + +2. Add a query for the dialog: +```typescript +@query('duplicate-tracks-dialog') +private duplicateDialog!: DuplicateTracksDialog; +``` + +3. Find the drag-drop handler `handlePlaylistDrop` (around line ~1823) that calls `await AddTracksToPlaylist(entry.summary.ID, payload.filePaths)` and wrap it with duplicate detection: +```typescript +// Replace the direct AddTracksToPlaylist call: +const result = await FindDuplicateTracksInPlaylist( + entry.summary.ID, + payload.filePaths, +); +const duplicates = result.Duplicates ?? []; +const unique = result.Unique ?? []; + +if (duplicates.length > 0) { + await this.updateComplete; + this.duplicateDialog.show(entry.summary.ID, duplicates, unique); + return; +} + +await AddTracksToPlaylist(entry.summary.ID, payload.filePaths); +await this.refreshPlaylists(); +``` + +4. Add `` to the playlist-view's render output. Find the location where `` and `` are rendered (likely near the end of the main render method) and add alongside them: +```html + this.refreshPlaylists()} +> +``` + +**Return type handling:** The Go method returns `([]DuplicateTrackInfo, []string, error)`. Wails will generate a TypeScript binding that returns an object. After running `wails generate module` in Task 1, check the generated types in `frontend/wailsjs/go/playlist/Service.d.ts` and `frontend/wailsjs/go/models.ts` to confirm the return shape. Go functions with multiple return values are mapped by Wails — typically a struct wrapper is needed. + +**Important adjustment:** Go functions exposed to Wails can only return `(T, error)` or `error`. Multiple return values won't work. So in Task 1, the method must return a struct: + +```go +type DuplicateCheckResult struct { + Duplicates []DuplicateTrackInfo `json:"Duplicates"` + Unique []string `json:"Unique"` +} + +func (s *Service) FindDuplicateTracksInPlaylist( + playlistID int64, + filePaths []string, +) (DuplicateCheckResult, error) +``` + +This way Wails generates `FindDuplicateTracksInPlaylist(playlistID: number, filePaths: string[]): Promise` and the frontend accesses `result.Duplicates` and `result.Unique`. + + + `npm run build` compiles. Test manually: drag tracks that are already in a playlist onto that playlist in the playlist-view sidebar — the duplicate dialog should appear. Using the context menu "Add to playlist" picker with tracks that already exist should also trigger the dialog. Adding tracks with no duplicates should work without any dialog. + + + Playlist-picker and playlist-view drag-drop both check for duplicates before adding. When duplicates found, the dialog appears for one-by-one resolution. When no duplicates, tracks are added directly as before. + + + + + + +1. `go build ./...` — backend compiles +2. `npm run build` (in frontend/) — frontend compiles +3. `wails build` — full app builds +4.

All changes are correctness improvements to existing code — no new features, no new dependencies. The changes are well-scoped: each requirement maps to a specific file location and can be implemented independently. + +The most complex requirement is CORR-09 (scan error separation), which touches multiple phases of the `Scan()` function and requires reclassifying many error paths. The second most complex is CORR-08 (artist credit link errors), which requires adding a database helper, a schema migration, and modifying the `cachedLinkArtist` function. The remaining three (CORR-05, CORR-06, CORR-07) are straightforward mechanical changes. + +A key discovery: the `artist_credit_artist` table currently has **no UNIQUE constraint** on `(artist_id, credit_id)`. The code relies on the in-memory `linkedCredits` cache to prevent duplicates within a scan, but across incremental scans, duplicate rows can be silently inserted. CORR-08 requires adding a UNIQUE constraint via a schema migration (migration 3) before the `isUniqueViolation` check becomes meaningful. + +**Primary recommendation:** Implement in order CORR-06 → CORR-05 → CORR-07 → CORR-08 → CORR-09 (simplest first, building toward the most complex scan refactor last). + +## Standard Stack + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| `log/slog` | stdlib (Go 1.25) | Structured logging | Already used project-wide; all error logging should use this | +| `errors` | stdlib (Go 1.25) | Error wrapping, `errors.As`, `errors.Join` | Already used project-wide for error accumulation | +| `modernc.org/sqlite` | v1.45.0 | CGo-free SQLite driver | Already the project's database driver; provides `*sqlite.Error` with `.Code()` | +| `modernc.org/sqlite/lib` | (transitive) | SQLite constants | Provides `SQLITE_CONSTRAINT_UNIQUE = 2067` | + +### Supporting +No additional libraries needed. All requirements are implementable with the existing stack. + +### Alternatives Considered +None — all decisions are locked to existing project tooling. + +## Architecture Patterns + +### Pattern 1: SQLite Error Code Detection (CORR-08) +**What:** Type-assert the error to `*sqlite.Error` using `errors.As`, then check `.Code()` against the specific SQLite extended result code. +**When to use:** Any time the codebase needs to distinguish specific SQLite failure modes (UNIQUE violations, FOREIGN KEY violations, etc.) +**Why not string matching:** The `isDuplicateColumnErr` helper at `database.go:329` uses string matching (`strings.Contains(err.Error(), "duplicate column name")`). This is fragile — error messages can change across driver versions. The `*sqlite.Error` type with `.Code()` is the stable, correct approach for constraint violations. + +```go +// backend/database/errors.go (new file) +package database + +import ( + "errors" + + "modernc.org/sqlite" + sqlite3 "modernc.org/sqlite/lib" +) + +// IsUniqueViolation reports whether err is a SQLite UNIQUE +// constraint violation (extended result code 2067). +func IsUniqueViolation(err error) bool { + var sqliteErr *sqlite.Error + if errors.As(err, &sqliteErr) { + return sqliteErr.Code() == sqlite3.SQLITE_CONSTRAINT_UNIQUE + } + return false +} +``` + +**Confidence:** HIGH — verified from `modernc.org/sqlite@v1.45.0/error.go` source: `Error` struct has `Code() int` method, and `modernc.org/sqlite/lib` exports `SQLITE_CONSTRAINT_UNIQUE = 2067`. + +### Pattern 2: MPRIS Callback Error Logging (CORR-07) +**What:** Replace discarded errors in MPRIS callback closures with log calls. +**When to use:** The four closures in `app.go:181-203` that call `player.Pause()` and `player.Seek()`. + +**Recommendation (Claude's Discretion):** +- **Log level: `Warn`** — these are non-fatal conditions where the player couldn't execute a command (e.g., no audio stream loaded when MPRIS sends Pause). They don't indicate bugs, but they're noteworthy for debugging. +- **Keep inline closures** — extracting to named methods would add indirection for simple one-line error checks. The closures are already short and clear. + +```go +// Current (app.go:183): +OnPause: func() { _ = yj.player.Pause() }, + +// After: +OnPause: func() { + if err := yj.player.Pause(); err != nil { + yj.logger.Warn("MPRIS Pause failed", "err", err) + } +}, +``` + +**Confidence:** HIGH — direct code inspection of app.go confirms exactly four closures need this treatment. + +### Pattern 3: Scan Warning Collection (CORR-09) +**What:** Accumulate non-fatal errors as structured warnings in `ScanMetrics.Warnings` instead of mixing them into the error return. +**When to use:** Throughout `Scan()` and its helper functions for non-fatal failures. + +**Thread safety note:** `ScanMetrics` already has a `sync.Mutex` protecting worker-pool fields. The `Warnings` slice will be appended from multiple goroutines (extraction workers, DB writer, orphan cleanup), so additions must go through a mutex-protected method. + +```go +// backend/library/metrics.go additions: + +// ScanWarning represents a non-fatal issue encountered during scanning. +type ScanWarning struct { + FilePath string `json:"filePath"` + Phase string `json:"phase"` // "extraction", "commit", "orphan" + Err error `json:"err"` +} + +// addWarning records a non-fatal scan issue. Safe for concurrent use. +func (m *ScanMetrics) addWarning(filePath, phase string, err error) { + m.mu.Lock() + defer m.mu.Unlock() + m.Warnings = append(m.Warnings, ScanWarning{ + FilePath: filePath, + Phase: phase, + Err: err, + }) +} +``` + +**Confidence:** HIGH — the existing `ScanMetrics.mu` pattern is proven (used by `addExtraction` and `addThumbnailTier`). + +### Pattern 4: Schema Migration for UNIQUE Constraint (CORR-08) +**What:** Add migration 3 to create a UNIQUE index on `artist_credit_artist(artist_id, credit_id)`. +**Why needed:** The `artist_credit_artist` table currently has NO UNIQUE constraint. Without it, the `isUniqueViolation` check would never trigger — the INSERT would always succeed (creating duplicates). The migration must also deduplicate existing rows. + +```go +// Migration 3: add UNIQUE constraint to artist_credit_artist +if version < 3 { + logger.Info("applying migration 3: artist_credit_artist unique constraint") + + // Remove duplicates first (keep lowest ID per pair). + if _, err := db.ExecContext(ctx, ` + DELETE FROM artist_credit_artist + WHERE id NOT IN ( + SELECT MIN(id) + FROM artist_credit_artist + GROUP BY artist_id, credit_id + ) + `); err != nil { + return fmt.Errorf("migration 3: could not deduplicate: %w", err) + } + + if _, err := db.ExecContext(ctx, ` + CREATE UNIQUE INDEX IF NOT EXISTS idx_artist_credit_artist_unique + ON artist_credit_artist(artist_id, credit_id) + `); err != nil { + return fmt.Errorf("migration 3: could not create unique index: %w", err) + } + + if _, err := db.ExecContext(ctx, "PRAGMA user_version = 3"); err != nil { + return fmt.Errorf("could not set user_version to 3: %w", err) + } +} +``` + +**Confidence:** HIGH — follows the existing migration pattern in `database.go:156-224`. SQLite supports `CREATE UNIQUE INDEX` for adding uniqueness constraints after table creation. + +### Anti-Patterns to Avoid +- **String matching for SQLite errors:** The existing `isDuplicateColumnErr` uses `strings.Contains(err.Error(), ...)`. Don't follow this pattern for CORR-08. Use `errors.As` + `.Code()` instead. +- **Mixing warnings and fatal errors in the same return:** The current `Scan()` accumulates everything into `scanErr` and returns it. After CORR-09, the error return must ONLY contain fatal errors; non-fatal issues go to `ScanMetrics.Warnings`. +- **Logging in multiple places:** CORR-05 specifies logging only in `OnDomReady`, not also in `OnStartup`. Don't add a second log call. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| SQLite error code detection | String matching on error messages | `errors.As` + `*sqlite.Error` + `.Code()` | Error messages are implementation details; codes are stable API | +| Error accumulation | Manual slice building | `errors.Join` (stdlib) | Already used in the project; handles nil correctly | + +**Key insight:** The project already uses `errors.Join` (app.go:154, library.go:321) and `log/slog` consistently. No new patterns needed — just applying existing patterns to currently-unhandled error paths. + +## Common Pitfalls + +### Pitfall 1: Missing UNIQUE Constraint for CORR-08 +**What goes wrong:** Adding `isUniqueViolation` without a UNIQUE constraint on `artist_credit_artist(artist_id, credit_id)` makes the check dead code — the INSERT never fails, duplicates silently accumulate. +**Why it happens:** The schema at `artist_credit_artist.sql` defines no uniqueness constraint. The code relies on the in-memory `linkedCredits` cache, which is per-scan. +**How to avoid:** Add migration 3 with a UNIQUE index AND deduplicate existing rows before creating the index. +**Warning signs:** If `isUniqueViolation` is never triggered in logs, the constraint is missing. + +### Pitfall 2: Thread Safety for ScanWarnings +**What goes wrong:** Appending to `ScanMetrics.Warnings` from multiple goroutines without synchronization causes data races. +**Why it happens:** The extraction worker pool runs concurrently with the DB writer goroutine. Both may produce warnings. +**How to avoid:** Use the existing `ScanMetrics.mu` mutex via an `addWarning` method, following the pattern of `addExtraction`. +**Warning signs:** `go test -race` failures in library scan tests. + +### Pitfall 3: Breaking the Fatal/Warning Boundary +**What goes wrong:** Reclassifying a fatal error as a warning causes the scan to "succeed" when it actually failed catastrophically (e.g., database connection lost). +**Why it happens:** Judgment call errors when categorizing error paths in CORR-09. +**How to avoid:** Strict rule: transaction begin/commit failures and context cancellation are ALWAYS fatal. Individual file operations (save, FTS index, orphan delete) are ALWAYS warnings. +**Warning signs:** `handleConfigUpdate` silently succeeding when the database is actually down. + +### Pitfall 4: MPRIS Callback Logger Access +**What goes wrong:** The MPRIS callbacks in `OnStartup` capture `yj.logger` in closures. If logger is nil, the app panics. +**Why it happens:** It can't — `yj.logger` is set in `NewYellowJacketApp` before `OnStartup` runs. But worth noting this is a closure capture, not a method call. +**How to avoid:** No action needed; just verify logger is never nil when closures execute. + +### Pitfall 5: cachedLinkArtist Warning Propagation +**What goes wrong:** If `cachedLinkArtist` returns an error, the caller (`processMetadata`) might abort the entire file import for a non-critical failure. +**Why it happens:** Artist-credit-artist linking is optional — the file should still be imported even if this link fails. +**How to avoid:** Per the CONTEXT.md decision, non-UNIQUE errors become scan warnings. The function should either accept a warnings collector or call `metrics.addWarning` directly. Given the function already has access to `l.logger` and logs warnings internally, the cleanest approach is to pass `metrics` and call `addWarning` for non-UNIQUE errors, keeping the existing "log and continue" pattern. + +## Code Examples + +### CORR-05: Startup Error Field Migration +```go +// backend/app.go — struct change +type YellowJacketApp struct { + // ... existing fields ... + startupErr error // replaces package-level var +} + +// backend/app.go — OnStartup change (line ~154) +// Before: +// startupErr = errors.Join(startupErr, ...) +// After: +// yj.startupErr = errors.Join(yj.startupErr, ...) + +// backend/app.go — OnDomReady change (line ~252) +// Before: +// if startupErr != nil { +// After: +// if yj.startupErr != nil { +``` + +### CORR-06: Config Permissions Fix +```go +// backend/config/config.go:152 +// Before: +err = os.WriteFile(c.filePath, confFileData, os.FileMode(int(0o666))) +// After: +err = os.WriteFile(c.filePath, confFileData, 0o644) +``` + +### CORR-07: MPRIS Error Logging (all four closures) +```go +// backend/app.go — OnStartup MPRIS callbacks +OnPause: func() { + if err := yj.player.Pause(); err != nil { + yj.logger.Warn("MPRIS Pause failed", "err", err) + } +}, +OnPlayPause: func() { + if yj.player.IsPlaying() { + if err := yj.player.Pause(); err != nil { + yj.logger.Warn("MPRIS PlayPause(pause) failed", "err", err) + } + } else { + yj.queue.Play() + } +}, +OnStop: func() { + if err := yj.player.Pause(); err != nil { + yj.logger.Warn("MPRIS Stop failed", "err", err) + } +}, +OnSeek: func(positionSec int) { + if err := yj.player.Seek(positionSec); err != nil { + yj.logger.Warn("MPRIS Seek failed", "err", err) + } +}, +``` + +### CORR-08: cachedLinkArtist with Error Checking +```go +// backend/library/library.go — updated cachedLinkArtist +func (l *Library) cachedLinkArtist( + q *sqlcgen.Queries, + cache *entityCache, + metrics *ScanMetrics, + name string, + creditID int64, +) { + // ... existing artist upsert logic unchanged ... + + linkKey := fmt.Sprintf("%d:%d", artist.ID, creditID) + if _, done := cache.linkedCredits[linkKey]; done { + return + } + + _, err = q.CreateArtistCreditArtist( + l.ctx, + sqlcgen.CreateArtistCreditArtistParams{ + ArtistID: artist.ID, + CreditID: creditID, + }, + ) + if err != nil { + if !database.IsUniqueViolation(err) { + l.logger.Warn( + "could not link artist to credit", + "artist", name, + "creditID", creditID, + "err", err, + ) + metrics.addWarning(name, "commit", fmt.Errorf( + "artist-credit link failed for %q: %w", name, err, + )) + } + // UNIQUE violation: link already exists in DB, not an error + } + + cache.linkedCredits[linkKey] = struct{}{} +} +``` + +### CORR-09: Error Reclassification in Scan() +```go +// Fatal errors (error return): +// - l.db.Queries.GetAllAudioFiles fails (line 199) +// - l.db.BeginTx fails (commitBatch, line 659) +// - tx.Commit fails (commitBatch, line 702) +// - l.ctx.Err() — context cancellation + +// Warnings (ScanMetrics.Warnings): +// - metadata extraction failures (line 429-439) +// - individual file save failures (commitBatch, line 691-698) +// - FTS indexing failures (saveAudioFile line 787-798, updateAudioFile line 866-893) +// - orphan delete failures (line 484-495) +// - orphan FTS delete failures (line 498-505) +// - WalkDir errors (line 319-328) +// - missing variant generation (line 518-523) +``` + +## State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +|--------------|------------------|--------------|--------| +| `strings.Contains(err.Error(), ...)` for SQLite errors | `errors.As` + `*sqlite.Error` + `.Code()` | Available since modernc.org/sqlite added `Error` type | Stable error detection, independent of message wording | +| Package-level error variables | Struct fields | Go best practice | Avoids global state, enables testing | +| `0o666` file permissions | `0o644` for config files | Unix convention | Prevents world-write on config files | + +## Open Questions + +1. **Should `isDuplicateColumnErr` be updated to use `*sqlite.Error`?** + - What we know: The existing helper at `database.go:329` uses string matching.

Individual `saveErr` values go to `metrics.addWarning(result.absolutePath, "commit", saveErr)`. + - Only the `tx.Commit()` failure (line 702-706) remains as a returned error — this is a fatal transaction failure. + - In `Scan()`, the caller at lines 383-391 still checks `batchErr` — since `commitBatch` now only returns fatal commit errors, rename the check to reflect this: if commitBatch returns an error, it's fatal. **Return immediately** from the DB writer goroutine with the fatal error set via `errMu`. + +4. **Orphan delete failures (lines 484-495):** Already logged but silently continued. Add `metrics.addWarning(path, "orphan", err)` alongside the existing log. The `return true` (continue iteration) stays. + +5. **Orphan FTS delete failures (lines 498-505):** Already logged but silently continued.

Add `metrics.addWarning("", "variant", err)` alongside the existing log. + +7. **FTS indexing failures in saveAudioFile (lines 787-798) and updateAudioFileMetadata (lines 866-893):** These are currently logged but don't return errors. Convert to warnings: add `metrics.addWarning(result.absolutePath, "commit", err)` alongside the existing log. Since `saveAudioFile` and `updateAudioFileMetadata` already receive `metrics`, this is straightforward. + +8. **Remove `errMu` and `scanErr` accumulation pattern.** After reclassification: + - `scanErr` should only contain fatal errors (context cancellation, transaction commit failures) + - `errMu` may still be needed if the DB writer goroutine sets a fatal error that Scan() reads. Keep `errMu` but only use it for fatal error paths. + - The extraction worker pool no longer writes to `scanErr` — all extraction failures are warnings. + +**CORR-08 Part 3 — Update cachedLinkArtist (backend/library/library.go):** + +Per CONTEXT.md decision: pass `metrics *ScanMetrics` as an additional parameter.

No production code changes except adding test files. + + + + +## Implementation Decisions + +### Test fixture strategy +- Per-test inline setup for queue — each test creates its own audio_file FK rows with minimal fields. Verbose but self-contained; a test failure tells you everything. +- t.TempDir() for config filesystem tests — real filesystem via Go's test temp dirs, auto-cleaned, tests actual TOML read/write. +- Simple mock TrackLoader struct defined locally in queue_test.go — only queue tests need it, keep it local. +- Player tests are pure logic only — no NewTestDB, no persistence round-trips. Volume conversion, clamp, state mapping only. Player persistence deferred to integration tests. + +### Player logic extraction +- Test existing pure logic in place — volume.go (UserVolume, Volume, clampVolume) is already cleanly separated. Write volume_test.go against it. No extraction from player.go. +- Include stateToMediaControls() — it's pure and trivial but documents the state mapping. Characterization value. +- Format detection tested in metadata package, not player — the code lives in metadata/decoder.go, tests belong there (decoder_test.go or similar). +- Do NOT extract anything new from player.go — lock-sensitive code must not be touched. Test what's already pure. + +### Coverage depth vs breadth +- Queue: edge cases first — empty queue, single track, last track, first track, remove current track. These are where bugs hide and refactoring breaks. +- Queue: dedicated move test cases — move forward, move backward, move current track, move to boundaries, move multiple tracks. MoveQueueTracks has the most complex index arithmetic. +- Queue: test InsertTracksAt index shifts — insert before/at/after current index, verify currentIndex adjusts correctly. Common off-by-one bug source. +- Queue: verify generateShuffleOrder() properties — all indices present, current track at index 0, no duplicates. Property-based validation. +- Queue: full persistence round-trip — SaveState → new Queue → RestoreState → verify all fields match (shuffle order, repeat mode, current index, track list). Critical for Phase 7 optimization safety. +- Config: test both sub-config validators independently AND the composed Config.Validate(). Pinpoints failures to specific validators. +- Config: include library.Config.Validate() path with t.TempDir() — test both valid directory (real temp dir) and invalid directory (nonexistent path). +- Player: 5-6 tests is sufficient — volume roundtrip, boundary values, clamp, state mapping. Quality over quantity. + +### Test organization +- Internal test packages (package queue, package config, package player) — queue tests need access to unexported fields (shuffleOrder, currentIndex, tracks) for setup and assertions. +- Mirror source file names — navigation_test.go tests navigation.go, persistence_test.go tests persistence.go, queue_test.go tests queue.go. Easy to find tests for any function. +- Sub-config tests in their respective packages — theme/config_test.go, tracklist/config_test.go, favorites/config_test.go, library/config_test.go. Config package tests the composed Config. +- t.Parallel() everywhere — NewTestDB gives isolated DB instances, pure logic tests have no shared state. Matches existing coverart/metadata convention. + +### Claude's Discretion +- Exact test case names and table-driven subtest structure +- How to organize table-driven tests vs individual test functions (per complexity) +- Specific assertion messages and error formatting +- Whether to use subtests within a single Test function or separate Test functions per behavior + + + + +## Specific Ideas + +- Queue persistence round-trip is the highest-priority safety net — Phase 7 (PERF-01) will change queue persistence from full table rewrite to incremental INSERT/DELETE.

Internal tests (`package library`) to access unexported fields +- `t.Parallel()` on all tests +- `database.NewTestDB(t)` for DB-backed tests +- Construct test data inline per CONTEXT.md decision (no shared metadata builders) +- Seed data via raw SQL (db.ExecContext) for explicit control + + + + + + + Task 1: Pure helper tests (no DB needed) + backend/library/scan_test.go + +Create `backend/library/scan_test.go` (package library — internal tests, access unexported functions). + +**Pure helper tests (no DB dependency):** + +1. `TestGetRecordingName` — table-driven subtests: + - Title present: tags.Title="Bohemian Rhapsody" → returns "Bohemian Rhapsody" + - Title empty, falls back to filename: tags.Title="", filePath="/music/song.mp3" → returns "song" + - Title empty, complex path: filePath="/music/Artist - Track.flac" → returns "Artist - Track" + + Create a minimal Library struct for calling: `lib := &Library{logger: slog.Default()}` (getRecordingName only uses l.logger indirectly — actually it doesn't use logger at all, just tags and filePath). + +2. `TestToNullInt64` — table-driven subtests: + - 0 → sql.NullInt64{Valid: false} + - 5 → sql.NullInt64{Int64: 5, Valid: true} + - -1 → sql.NullInt64{Int64: -1, Valid: true} (negative is non-zero) + +3. `TestToNullString` — table-driven subtests: + - "" → sql.NullString{Valid: false} + - "rock" → sql.NullString{String: "rock", Valid: true} + +4. `TestSplitGenres` — table-driven subtests: + - Empty string → nil + - Single genre "Rock" → ["Rock"] + - Multiple genres "Rock||Jazz||Blues" → ["Rock", "Jazz", "Blues"] + - Two genres "Electronic||Ambient" → ["Electronic", "Ambient"] + +5. `TestMapTrackRow` — single test, verify all 16 fields mapped correctly: + - Pass specific values for all parameters including sql.NullInt64 for track_number/disc_number + - Assert Track struct has correct values for all fields + - Verify TrackLength is string-formatted milliseconds (e.g., int64 180000 → "180000") + - Verify Genre is split from "Rock||Jazz" → []string{"Rock", "Jazz"} + - Verify NullInt64 fields: Valid=true extracts Int64, Valid=false yields 0 + +Follow established patterns: `t.Parallel()`, table-driven subtests with `t.Run()`, standard library testing (no testify), `TestFunctionName_Scenario` naming. + + + cd backend && go test -race -run "TestGetRecordingName|TestToNullInt64|TestToNullString|TestSplitGenres|TestMapTrackRow" ./library/ -v -count=1 + + 5 pure helper test functions pass: getRecordingName falls back to filename sans

"/test"}, db)` +- Returns both for direct DB seeding in tests + +**Entity cache tests (DB-backed):** + +6. `TestCachedUpsertArtistCredit` — test cache hit behavior: + - Create library + DB, create fresh entityCache via `newEntityCache()` + - Call `cachedUpsertArtistCredit(q, cache, "Queen")` — first call hits DB, returns ArtistCredit with valid ID + - Call again with same name — verify returns same ID (cache hit) + - Call with different name "Beyoncé" — verify returns different ID + - Verify cache map has 2 entries + +7. `TestCachedLinkArtist` — test artist-credit link creation and dedup: + - Create library + DB + cache + - First: upsert an artist credit to get a creditID + - Call `cachedLinkArtist(q, cache, metrics, "Queen", creditID)` — creates artist + link + - Call again with same args — should skip (linkedCredits cache hit, no duplicate INSERT) + - Verify linkedCredits cache has exactly 1 entry + - Verify the artist exists in the artists cache + +8. `TestCachedLinkArtist_MultiCredit` — test same artist in different credits: + - Upsert two different artist credits: "Queen" (creditID=1) and "Queen feat. David Bowie" (creditID=2) + - Call cachedLinkArtist for "Queen" with creditID=1 + - Call cachedLinkArtist for "Queen" with creditID=2 + - Verify artist cached once (artists map has 1 "Queen" entry) but linkedCredits has 2 entries ("artistID:1" and "artistID:2") + +9. `TestCachedUpsertGenre` — test genre cache: + - Call `cachedUpsertGenre(q, cache, "Rock")` — first call creates genre + - Call again — returns same ID from cache + - Verify cache has 1 entry + +10. `TestResolveReleaseGroup` — test release group resolution + cover art update: + - Call with tags.Album="A Night at the Opera", no cover art → returns valid NullInt64 + - Call again with same album but with cover art → should update the cached release group's cover art + - Call with tags.Album="" → returns invalid NullInt64 + +11. `TestResolveReleaseGroup_CacheHit` — separate test for pure cache behavior: + - Pre-populate cache.releaseGroups with a known release group + - Call resolveReleaseGroup — verify returns cached ID without DB query + - This documents that the cache is the first check + +**Orphan cleanup test (DB-level):** + +12. `TestOrphanDeletion` — test DeleteAudioFile + DeleteSearchIndex at DB level: + - Seed an audio_file row + search_index entry via raw SQL + - Call `db.Queries.DeleteAudioFile(ctx, id)` — verify audio_files row gone + - Call `db.DeleteSearchIndex(id)` — verify search_index entry gone + - Verify a SearchFTS query no longer returns the deleted track + +**Missing fields / empty metadata test:** + +13. `TestEntityCache_EmptyFields` — verify behavior with missing metadata: + - Call cachedUpsertArtistCredit with empty name "" — documents what happens (likely creates a "" credit or errors) + - Call resolveReleaseGroup with empty Album — should return invalid NullInt64 + - Test resolveAlbumArtistCredit when AlbumArtist=="" — should reuse track artist credit + +All tests use `t.Parallel()`.

The codebase has a well-defined 5-table JOIN pattern (audio_files → recordings → artist_credit → release_group_recordings subquery → release_groups) duplicated across **10+ locations** in both hand-crafted Go SQL and sqlc query files. This pattern can be consolidated into a single SQLite VIEW named `track_metadata`. + +Verification confirms that sqlc v1.30.0 (the project's current version) fully supports querying from VIEWs and using `sqlc.slice()` for IN clauses with the SQLite engine — both features were tested directly against the project's toolchain. The event codegen task is straightforward: `go/ast` can parse the 4 const blocks in `events.go` (21 constants) and produce the matching TypeScript `events.ts` output. The existing `codegen-check` lefthook hook currently runs `go generate ./...` which was observed to hang in earlier phases (templ generation timeout), but testing now shows it completes in under 1 second — the fix may simply be wiring the new generator into the existing hook and verifying it works end-to-end. + +**Primary recommendation:** Create the `track_metadata` VIEW as migration 4, update all search/rebuild queries to use it, write the event codegen tool using `go/ast`, migrate `lookupChunk` to sqlc with `sqlc.slice()`, and annotate all remaining hand-crafted SQL with `// SAFETY:` comments. + + +## User Constraints (from CONTEXT.md) + +### Locked Decisions +- Single VIEW named `track_metadata` with all 16 columns (file_path, length, title, artist, album, track_number, disc_number, genre, year, composer, file_type, sample_rate, bit_depth, channels, bitrate, file_size) +- VIEW rooted on `audio_files` (not `search_index`) so it's usable for both search queries (JOIN search_index to VIEW) and index rebuilds (SELECT directly from VIEW) +- Created as migration 4 (next sequential PRAGMA user_version bump) +- Lightweight search queries (SearchFTS, SearchFTSByFilename) SELECT only the 5 columns they need from the VIEW — SQLite optimizes unused columns away +- RebuildSearchIndex and migration2 INSERT INTO search_index use the VIEW instead of duplicating the JOIN +- Go constants in `backend/events/events.go` are the source of truth +- Generator written in Go, using `go/ast` to parse the const block from events.go +- Wired into `go generate` via `//go:generate` directive on events.go +- Output format matches current `frontend/src/events.ts` structure exactly: `export const Events = { ... } as const;` — zero changes needed in frontend import sites +- Fix the existing `codegen-check` lefthook pre-commit hook (currently hangs) to run the generator and diff the output — fail if TypeScript file is stale +- Note: `LibraryConfigChanged` exists in Go but is missing from TypeScript — the generator will fix this automatically +- Migrate `lookupChunk()` query fully to sqlc: the SELECT + JOINs + `sqlc.slice()` for the IN clause — use the new `track_metadata` VIEW instead of hand-crafted JOINs +- `insertTrackBatch()` (multi-row VALUES with variable row count) stays hand-crafted — sqlc cannot generate variable-length batch INSERTs.

File naming should sort after the tables it depends on (alphabetical ordering puts `track_metadata_view.sql` after all table schemas). + +**Important:** `CREATE VIEW IF NOT EXISTS` is the correct DDL for the schema file. The VIEW will also be created by migration 4 for existing databases, but the schema file ensures sqlc knows about it and new databases get it automatically. + +### Pattern 1: VIEW Definition +**What:** The `track_metadata` VIEW consolidates the 5-table JOIN into a reusable SQL object +**When to use:** Any query needing audio file metadata with title/artist/album +**Example:** +```sql +-- In backend/database/sql/schemas/track_metadata_view.sql +CREATE VIEW IF NOT EXISTS track_metadata AS +SELECT + af.id, + af.file_path, + af.length_milliseconds, + COALESCE(r.name, '') AS title, + COALESCE(ac.text, '') AS artist_name, + r.track_number, + r.disc_number, + COALESCE(rg.name, '') AS album, + CAST(COALESCE( + (SELECT GROUP_CONCAT(g.name, '||') + FROM recording_genres rg_sub + JOIN genres g ON rg_sub.genre_id = g.id + WHERE rg_sub.recording_id = r.id), + '' + ) AS TEXT) AS genre, + COALESCE(r.year, 0) AS year, + COALESCE(r.composer, '') AS composer, + COALESCE(ft.extension, '') AS file_type, + af.sample_rate, + af.bit_depth, + af.channels, + af.bitrate, + af.file_size +FROM audio_files af +LEFT JOIN recordings r ON af.recording_id = r.id +LEFT JOIN artist_credit ac ON r.artist_credit_id = ac.id +LEFT JOIN ( + SELECT recording_id, + MIN(release_group_id) AS release_group_id + FROM release_group_recordings + GROUP BY recording_id +) rgr ON r.id = rgr.recording_id +LEFT JOIN release_groups rg ON rgr.release_group_id = rg.id +LEFT JOIN file_types ft ON af.file_type_id = ft.id; +``` + +**Note:** The VIEW includes `af.id` (needed for FTS5 rowid matching and queue lookups). The `id` column is included in the VIEW but queries don't have to select it. It also uses LEFT JOIN throughout (not INNER JOIN) to match the existing pattern — some audio files may have recording_id=0 (no metadata yet). + +### Pattern 2: Search Queries Using VIEW +**What:** FTS5 search queries JOIN search_index to the VIEW +**When to use:** SearchFTS, SearchFTSByFilename, SearchFTSTracks +**Example:** +```sql +-- Hand-crafted (stays in search.go — FTS5 MATCH unsupported by sqlc) +SELECT + tm.file_path, + tm.length_milliseconds, + tm.title, + tm.artist_name, + tm.album +FROM search_index si +JOIN track_metadata tm ON tm.id = si.rowid +WHERE search_index MATCH ? +ORDER BY rank +LIMIT ? +``` + +### Pattern 3: Rebuild Using VIEW +**What:** RebuildSearchIndex selects directly from VIEW +**When to use:** Full FTS5 index rebuild, migration 2 FTS population +**Example:** +```sql +-- Hand-crafted (stays in search.go — FTS5 INSERT unsupported by sqlc) +INSERT INTO search_index(rowid, file_path, title, artist, album) +SELECT id, file_path, title, artist_name, album +FROM track_metadata +``` + +### Pattern 4: sqlc.slice() for Batch Lookups +**What:** Queue lookupChunk migrated to sqlc query using VIEW + sqlc.slice() +**When to use:** Batch file path lookups in queue persistence +**Example:** +```sql +-- In backend/database/sql/queries/queue.sql (or audio_files.sql) +-- name: LookupTrackMetaBatch :many +SELECT id, file_path, title, artist_name +FROM track_metadata +WHERE file_path IN (sqlc.slice('paths')); +``` + +**Critical note:** The generated sqlc code does NOT handle chunking — it generates a single query with all placeholders. The caller (`lookupTrackMetaBatch`) must still chunk the paths array at `maxSQLiteVars = 900` before calling the generated method. The chunking loop stays; only the inner SQL construction moves to sqlc. + +### Pattern 5: Event Codegen with go/ast +**What:** Go program reads events.go const blocks, generates events.ts +**When to use:** Automated via `//go:generate` directive +**Example structure:** +```go +// backend/events/gen_events_ts.go (or cmd/gen-events/main.go) +package main + +import ( + "go/ast" + "go/parser" + "go/token" + // ... +) + +func main() { + fset := token.NewFileSet() + f, err := parser.ParseFile(fset, "events.go", nil, parser.ParseComments) + // Walk AST, extract const declarations + // Group by comment blocks (Playback, Queue, Config, Playlist, Library) + // Generate TypeScript output matching current format +} +``` + +### Anti-Patterns to Avoid +- **Don't put the VIEW in a migration-only file without the schema file:** sqlc needs the VIEW definition in the schema directory to generate code against it. The migration creates it for existing DBs; the schema file teaches sqlc about it. +- **Don't remove chunking from lookupTrackMetaBatch:** `sqlc.slice()` doesn't auto-chunk. SQLite has a bind variable limit (~32766 in newer versions, but the project uses a conservative 900). The chunking loop must remain. +- **Don't try to make FTS5 queries use sqlc:** FTS5 MATCH syntax, `content=''` virtual tables, and rank ordering are unsupported by sqlc's parser. These must stay hand-crafted. +- **Don't change the migration2 code to use the VIEW for DB version < 4:** Migration 2 runs before migration 4 in sequence. For databases upgrading from version 1→4, migration 2 must still work without the VIEW. Only databases already at version ≥ 4 (including fresh DBs) should use the VIEW in the rebuild path. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Go AST parsing | Regex/string matching on events.go | `go/ast` + `go/parser` + `go/token` | Handles comments, multiline, formatting robustly | +| SQL IN clause placeholder construction | `fmt.Sprintf` with manual `?` joining | `sqlc.slice()` | Generates correct placeholder expansion; type-safe | +| Duplicate JOIN patterns | Copy-paste SQL across files | SQLite VIEW | Single source of truth; SQLite optimizes unused columns | + +**Key insight:** The manual placeholder construction in `lookupChunk` is exactly the pattern `sqlc.slice()` was designed to replace — sqlc generates the same `strings.Replace` / `strings.Repeat` code but with type safety and no manual `args` slice building. + +## Common Pitfalls + +### Pitfall 1: Migration Ordering with VIEW +**What goes wrong:** migration2 tries to SELECT from `track_metadata` VIEW before migration 4 creates it +**Why it happens:** Migrations run sequentially by version number. A database at version 1 runs migration 2 (which populates FTS) before migration 4 (which creates the VIEW). +**How to avoid:** Keep the existing inline JOIN in `migration2BasenameAndFTS`. Only the `RebuildSearchIndex` function (called at runtime, not during migration) should use the VIEW. The VIEW schema file handles fresh databases; migration 4 handles existing databases. +**Warning signs:** `no such table: track_metadata` error during migration + +### Pitfall 2: sqlc Schema File Ordering +**What goes wrong:** sqlc fails to parse the VIEW definition because it references tables not yet defined +**Why it happens:** sqlc processes schema files in filesystem order. If `track_metadata_view.sql` sorts before the tables it references, sqlc can't resolve them. +**How to avoid:** Name the file so it sorts after all dependencies. `track_metadata_view.sql` sorts after `recordings.sql`, `release_groups.sql`, etc. (all start with lowercase letters before 't'). Alternatively, prefix with `zz_` if needed, but alphabetical ordering of `track_metadata_view.sql` already works. +**Warning signs:** sqlc generate errors about unknown tables/columns + +### Pitfall 3: VIEW Column Mismatch with Existing Queries +**What goes wrong:** Queries that used INNER JOINs (e.g., `GetAllTracksWithFullMetadata` uses `JOIN recordings r` not `LEFT JOIN`) return different results when switched to the VIEW (which uses LEFT JOINs) +**Why it happens:** The VIEW uses LEFT JOINs to handle audio files without metadata. Existing sqlc queries that use INNER JOINs implicitly filter out unmatched rows. +**How to avoid:** Only replace queries that already use LEFT JOINs (search queries, playlist metadata queries, SearchAudioFilesByBasename). Leave queries with intentional INNER JOINs (like `GetAllTracksWithFullMetadata`) as-is, or add `WHERE r.id IS NOT NULL` to preserve INNER JOIN semantics. Carefully review each query's JOIN type before converting. +**Warning signs:** Extra rows with empty metadata appearing in results + +### Pitfall 4: codegen-check Hook Scope +**What goes wrong:** The event generator is added to `go generate` but the codegen-check hook still runs the full `go generate ./...` which includes templ and sqlc, making it slow +**Why it happens:** The hook runs all generators, not just the event one +**How to avoid:** The hook currently runs `go generate ./...` and then diffs. This approach is actually fine — testing shows `go generate ./...` completes in <1 second when nothing has changed. The hanging issue from earlier phases appears to be resolved. Verify the hook works end-to-end after wiring in the new generator. +**Warning signs:** Hook taking >5 seconds (should be <2s) + +### Pitfall 5: sqlc.slice() Empty Slice Behavior +**What goes wrong:** Passing an empty slice to a `sqlc.slice()` query +**Why it happens:** The generated code replaces the placeholder with `NULL` for empty slices, which means `WHERE file_path IN (NULL)` — this matches nothing (correct behavior), but the caller should still handle it +**How to avoid:** The chunking logic in `lookupTrackMetaBatch` already handles empty input (returns empty map). The sqlc-generated code also handles empty slices gracefully (returns empty results). No action needed, but be aware of the behavior. +**Warning signs:** N/A — behavior is correct + +### Pitfall 6: Generated TypeScript File Must Be Deterministic +**What goes wrong:** The event generator produces different output on different runs (e.g., map iteration order), causing the codegen-check hook to always fail +**Why it happens:** Go maps don't have deterministic iteration order +**How to avoid:** Use `ast.Inspect` or iterate `f.Decls` in source order (AST preserves declaration order). Don't collect into a map and iterate — iterate the AST directly and emit in declaration order. +**Warning signs:** `codegen-check` hook always shows diff even when events.go hasn't changed + +## Code Examples + +### Example 1: Migration 4 — Create track_metadata VIEW +```sql +-- In migration 4 (backend/database/database.go) +CREATE VIEW IF NOT EXISTS track_metadata AS +SELECT + af.id, + af.file_path, + af.length_milliseconds, + COALESCE(r.name, '') AS title, + COALESCE(ac.text, '') AS artist_name, + r.track_number, + r.disc_number, + COALESCE(rg.name, '') AS album, + CAST(COALESCE( + (SELECT GROUP_CONCAT(g.name, '||') + FROM recording_genres rg_sub + JOIN genres g ON rg_sub.genre_id = g.id + WHERE rg_sub.recording_id = r.id), + '' + ) AS TEXT) AS genre, + COALESCE(r.year, 0) AS year, + COALESCE(r.composer, '') AS composer, + COALESCE(ft.extension, '') AS file_type, + af.sample_rate, + af.bit_depth, + af.channels, + af.bitrate, + af.file_size +FROM audio_files af +LEFT JOIN recordings r ON af.recording_id = r.id +LEFT JOIN artist_credit ac ON r.artist_credit_id = ac.id +LEFT JOIN ( + SELECT recording_id, + MIN(release_group_id) AS release_group_id + FROM release_group_recordings + GROUP BY recording_id +) rgr ON r.id = rgr.recording_id +LEFT JOIN release_groups rg ON rgr.release_group_id = rg.id +LEFT JOIN file_types ft ON af.file_type_id = ft.id; +``` + +### Example 2: Consolidated SearchFTS Using VIEW +```go +// In search.go — replaces the inline 5-table JOIN +rows, err := d.db.QueryContext(d.Ctx, ` + SELECT + tm.file_path, + tm.length_milliseconds, + tm.title, + tm.artist_name, + tm.album + FROM search_index si + JOIN track_metadata tm ON tm.id = si.rowid + WHERE search_index MATCH ? + ORDER BY rank + LIMIT ? +`, ftsQuery, limit) +``` + +### Example 3: Consolidated RebuildSearchIndex Using VIEW +```go +// In search.go — replaces inline JOIN for rebuild +_, err := d.db.ExecContext(d.Ctx, ` + INSERT INTO search_index(rowid, file_path, title, artist, album) + SELECT id, file_path, title, artist_name, album + FROM track_metadata +`) +``` + +### Example 4: sqlc Query for lookupChunk Replacement +```sql +-- In backend/database/sql/queries/queue.sql (or a new track_metadata.sql) +-- name: LookupTrackMetaByPaths :many +SELECT id, file_path, title, artist_name +FROM track_metadata +WHERE file_path IN (sqlc.slice('paths')); +``` + +### Example 5: Event Generator Core Logic +```go +// Using go/ast to extract constants from events.go +fset := token.NewFileSet() +f, err := parser.ParseFile(fset, eventsGoPath, nil, parser.ParseComments) +if err != nil { + log.Fatal(err) +} + +type eventConst struct { + Name string + Value string +} + +var events []eventConst + +ast.Inspect(f, func(n ast.Node) bool { + genDecl, ok := n.(*ast.GenDecl) + if !ok || genDecl.Tok != token.CONST { + return true + } + for _, spec := range genDecl.Specs { + vs, ok := spec.(*ast.ValueSpec) + if !ok || len(vs.Names) == 0 || len(vs.Values) == 0 { + continue + } + lit, ok := vs.Values[0].(*ast.BasicLit) + if !ok || lit.Kind != token.STRING { + continue + } + name := vs.Names[0].Name + value := strings.Trim(lit.Value, `"`) + events = append(events, eventConst{Name: name, Value: value}) + } + return true +}) +``` + +### Example 6: SAFETY Comment Examples +```go +// SAFETY: FTS5 MATCH syntax unsupported by sqlc.

Sqlc queries are already managed and less prone to drift. + - What's unclear: Whether updating sqlc queries provides enough benefit to justify the churn and testing. + - Recommendation: Update `SearchAudioFilesByBasename` (exact same pattern). Leave playlist/genre queries as-is (they have additional JOINs the VIEW doesn't cover). This is Claude's discretion per CONTEXT.md. + +2. **Where should the event generator Go file live?** + - What we know: It needs to be a `main` package (standalone executable for `go:generate`). Options: `backend/events/cmd/gen-events-ts/main.go` or `cmd/gen-events-ts/main.go` or inline in `backend/events/`. + - What's unclear: Project convention for codegen tools (none exist yet). + - Recommendation: `backend/events/cmd/genevents/main.go` — keeps it close to the source of truth. The `//go:generate` directive on events.go runs it. + +3. **codegen-check hook — is it actually fixed?** + - What we know: `go generate ./...` now completes in <1 second in testing. Previous hanging was during Phase 2 (Feb 2026). + - What's unclear: Whether the fix was a templ version update, environment change, or something else. + - Recommendation: After wiring the event generator, test the full hook manually (`lefthook run pre-commit`) before declaring it fixed.

The VIEW's columns `title` and `artist_name` match the data lookupChunk currently fetches via its inline JOIN. + + 2. Run `go tool sqlc generate` from `backend/database/` to generate the Go code. + + 3. Update `backend/queue/persistence.go`: + + a. Replace the `lookupChunk` method body. Instead of building `fmt.Sprintf` placeholders, call the sqlc-generated `LookupTrackMetaByPaths` method: + ```go + func (q *Queue) lookupChunk( + paths []string, + result map[string]trackMeta, + ) { + if len(paths) == 0 { + return + } + + rows, err := q.db.Queries.LookupTrackMetaByPaths(q.db.Ctx, paths) + if err != nil { + q.logger.Error("Batch metadata lookup failed", "err", err) + return + } + + for _, row := range rows { + result[row.FilePath] = trackMeta{ + AudioFileID: row.ID, + FilePath: row.FilePath, + Title: row.Title, + Artist: row.ArtistName, + } + } + } + ``` + + b. The `lookupTrackMetaBatch` function stays unchanged — it still chunks at `maxSQLiteVars` and calls `lookupChunk` per chunk. The chunking is still necessary because `sqlc.slice()` does NOT auto-chunk. + + c. Remove the now-unused imports: `"fmt"` and `"strings"` may become unused if `insertTrackBatch` is the only remaining user. Check import usage — `fmt` is still needed for `insertTrackBatch` (line ~200 `fmt.Errorf`), and `strings` is still needed for `insertTrackBatch` (line ~196 `strings.Join`). Keep both if still referenced. + + 4. Verify the field name mapping is correct: + - VIEW column `id` → sqlc field `ID` → `trackMeta.AudioFileID` + - VIEW column `file_path` → sqlc field `FilePath` → `trackMeta.FilePath` + - VIEW column `title` → sqlc field `Title` → `trackMeta.Title` + - VIEW column `artist_name` → sqlc field `ArtistName` → `trackMeta.Artist` + + 5.

No position shifting needed because AddTrack always appends to the end. + +2. `persistAddTracks(tracks []Track)` — Inserts multiple tracks at consecutive positions at the end of the queue. Use the same `InsertQueueTrack` in a loop (these are appends, so no position shifting needed). Wrap in a transaction for atomicity (use `q.db.BeginTx()`, `q.db.Queries.WithTx(tx)`). + +3. `persistInsertTracks(tracks []Track, insertPos int)` — For insert-at-position operations. In a transaction: (a) Call `ShiftQueuePositionsUp` with `insertPos` to make room — but note `ShiftQueuePositionsUp` shifts by 1, so for N tracks, we need to shift by N. Since the sqlc query only shifts by 1, use a hand-crafted UPDATE: `UPDATE queue_tracks SET position = position + ? WHERE position >= ?` with args (len(tracks), insertPos). Add a `// SAFETY:` comment explaining why. (b) Insert each track using `InsertQueueTrack` with positions `insertPos`, `insertPos+1`, ..., `insertPos+N-1`. + +4. `persistRemoveTrack(position int)` — In a transaction: (a) Call `RemoveQueueTrackByPosition(position)`. (b) Call `ShiftQueuePositionsDown(position)` to close the gap. + +5. `persistRemoveTracks(positions []int)` — For multi-track removal. Since multiple position shifts interact, use the full `persistTracks()` rewrite for simplicity (the bulk path is acceptable for multi-remove — the user decision specified bulk operations keep the full rewrite). Just call `persistTracks()` directly. + +**In `queue.go`, update these methods to use incremental persistence instead of `commitMutation`:** + +1. `AddTrack` — Replace `q.commitMutation(false)` with: `q.persistAddTrack(track)` then `q.persistState()`.

No reindex needed. + +3. `InsertNext` — Replace `q.commitMutation(true)` with: call `q.reindexPositions()` first, then `q.persistInsertTracks([]Track{track}, insertPos)` then `q.persistState()`. The reindex ensures in-memory positions are correct for subsequent operations. + +4. `InsertNextTracks` — Replace `q.commitMutation(true)` with: call `q.reindexPositions()` first, then `q.persistInsertTracks(newTracks, insertPos)` then `q.persistState()`. + +5. `InsertTracksAt` — Replace `q.commitMutation(true)` with: call `q.reindexPositions()` first, then `q.persistInsertTracks(newTracks, index)` then `q.persistState()`. + +6. `RemoveTrack` — Replace `q.commitMutation(true)` with: call `q.persistRemoveTrack(position)` then `q.reindexPositions()` then `q.persistState()`. + +7. `RemoveTracks` — Replace `q.commitMutation(true)` with: call `q.reindexPositions()` then `q.persistTracks()` (full rewrite, per user decision for bulk ops) then `q.persistState()`. + +**Keep `commitMutation` for**: `Clear`, `MoveQueueTracks`, `resolveRemainingTracks` — bulk operations that still do full rewrites per user decision. + +**For the hand-crafted SQL in `persistInsertTracks`:** Use `tx.ExecContext(q.db.Ctx, "UPDATE queue_tracks SET position = position + ? WHERE position >= ?", count, insertPos)` with a `// SAFETY: Multi-row position shift by variable N unsupported by sqlc (shift queries only shift by 1). Bind variables match args; no string interpolation.` comment. + +**Important:** Shuffle order regeneration was handled by `commitMutation`. For all the methods that previously called `commitMutation` with reindex=true, `generateShuffleOrder()` was also called if shuffleMode was active. Continue this behavior: after the incremental persist, check `q.shuffleMode` and call `q.generateShuffleOrder()` if true. For methods that called `commitMutation(false)` (AddTrack, AddTracks), shuffle order regeneration was also done if active — preserve this. + +**Verification approach:** Existing persistence roundtrip tests in `persistence_test.go` exercise `SaveState`/`RestoreState` which uses `persistTracks` (full rewrite).

Inside `resolveRemainingTracks`, build the exclusion set from `phase1Meta` keys. Filter `filePaths` to get only the paths NOT in `phase1Meta` before calling `lookupTrackMetaBatch`: + ```go + // Exclude paths already resolved in Phase 1. + var unresolvedPaths []string + for _, fp := range filePaths { + if _, alreadyResolved := phase1Meta[fp]; !alreadyResolved { + unresolvedPaths = append(unresolvedPaths, fp) + } + } + + // Only look up paths that Phase 1 didn't cover. + remainingMeta := q.lookupTrackMetaBatch(unresolvedPaths) + + // Merge Phase 1 results into the lookup. + for k, v := range phase1Meta { + remainingMeta[k] = v + } + ``` + +3. The rest of the method (building tracks from `allMeta`, finding `playingPath`, calling `commitMutation`) uses `remainingMeta` instead of `allMeta`.

Scroll through the track list, cover grid, and queue panel rapidly. +**Expected:** Smooth scrolling with no visible jank, stuttering, or dropped frames. DOM inspector should show only ~20-50 rendered rows at any time (virtualization working). +**Why human:** Jank perception is a runtime visual behavior that cannot be verified through static code analysis. + +### 2. View Switching Speed + +**Test:** Switch rapidly between tracks, albums, artists, and genres views. +**Expected:** Instant view transitions with no loading spinners or blank screens. Data is pre-cached via deferred eagerFetch. +**Why human:** Transition speed is a runtime behavior affected by data size, browser rendering, and perceived responsiveness. + +### 3. Search Debounce Feel + +**Test:** Type rapidly in the search bar, then stop. Clear the search. +**Expected:** Characters appear instantly in the input.

Running the app with `go test -race` produces zero data race reports for SetContext calls in queue, library, playlist, and player packages - 2. Queue.SetContext(), Library.SetContext(), and Playlist.Service.SetContext() each acquire their mutex before writing the ctx field - 3. Player.SetContext() uses a single lock acquisition instead of the double-lock pattern - 4. Concurrent calls to SetContext from multiple goroutines do not corrupt shared state -**Plans:** 1 plan -Plans: -- [x] 01-01-PLAN.md — Add mutex protection to all SetContext methods and collapse Player double-lock - -### Phase 2: Backend Correctness -**Goal:** All known error handling gaps are closed, configuration is secure, and the backend reports problems honestly instead of swallowing them -**Depends on:** Phase 1 (race-free code is prerequisite for reliable error paths) -**Requirements:** CORR-05, CORR-06, CORR-07, CORR-08, CORR-09 -**Success Criteria** (what must be TRUE): - 1. The package-level `startupErr` variable no longer exists; startup errors are stored in a YellowJacketApp struct field - 2. Config files are written with 0o644 permissions (owner read/write, group/other read-only) - 3. MPRIS lifecycle callback errors (Pause, Seek) appear in the application log instead of being silently discarded - 4. Artist credit link creation checks the actual error — only UNIQUE constraint violations are ignored, all other errors are surfaced - 5. Library.Scan() returns warnings (skipped files, partial failures) in ScanMetrics and fatal errors (database failures) in the error return, so callers can distinguish between "scan completed with issues" and "scan failed" -**Plans:** 2 plans -Plans: -- [x] 02-01-PLAN.md — Fix startupErr global state, config permissions, and MPRIS callback error logging -- [x] 02-02-PLAN.md — Add IsUniqueViolation helper, migration 3, and separate scan warnings from fatal errors - -### Phase 3: Test Infrastructure -**Goal:** A reliable, production-mirroring test foundation exists so that all subsequent test phases can write database-backed tests with confidence -**Depends on:** Phase 1 (race-free code required for `-race`-clean test runs), Phase 2 (correct error handling needed for accurate test assertions) -**Requirements:** TEST-01, PERF-04 -**Success Criteria** (what must be TRUE): - 1. `database.NewTestDB(t)` returns a clean in-memory SQLite database that applies the same migrations and PRAGMAs as the production `NewDB()` - 2. Production SQLite connection applies `synchronous=NORMAL`, `cache_size=-8000`, and `mmap_size=67108864` PRAGMAs at database open - 3. Each test gets an isolated database instance — no shared state between test functions - 4. Tests using `NewTestDB` pass with `-race` flag enabled -**Plans:** 1 plan -Plans: -- [x] 03-01-PLAN.md — Extract shared applyPRAGMAs, add production PRAGMAs, and create NewTestDB helper - -### Phase 4: Queue, Config & Player Tests -**Goal:** The queue, config, and player packages have comprehensive unit tests that characterize current behavior and serve as a safety net for later refactoring -**Depends on:** Phase 3 (queue tests need NewTestDB for persistence tests) -**Requirements:** TEST-02, TEST-04, TEST-05 -**Success Criteria** (what must be TRUE): - 1. Queue package has ~15-20 tests covering SetQueue, Next, Previous, shuffle mode, repeat modes (off, one, all), and state persistence across save/load cycles - 2. Config package has ~8-10 tests covering load/save roundtrip fidelity, validation rule enforcement, default value application, and graceful handling of missing or empty config files - 3. Player pure logic (UserVolume↔Volume conversion, state serialization/deserialization, format detection from file extension) is extracted into standalone functions with ~5-8 unit tests - 4. All tests in this phase pass with `-race` flag enabled -**Plans:** 2 plans -Plans: -- [x] 04-01-PLAN.md — Queue package unit tests (core operations, navigation, persistence roundtrip) -- [x] 04-02-PLAN.md — Config + Player tests (sub-config validators, load/save roundtrip, volume conversion, state mapping) - -### Phase 5: Database & Library Tests -**Goal:** Database queries (especially FTS5 search) and library scan logic have unit tests that lock down current behavior before SQL consolidation and performance optimization -**Depends on:** Phase 3 (database tests need NewTestDB), Phase 4 (queue tests validate persistence patterns reused here) -**Requirements:** TEST-03, TEST-06 -**Success Criteria** (what must be TRUE): - 1. Database package has ~10-15 tests covering FTS5 search (basic terms, empty query, special characters, multi-word), search index rebuild, and schema migration application - 2. Library scan logic has ~10-15 tests covering metadata extraction processing, entity cache hit/miss behavior, and orphan track cleanup - 3. FTS5 search tests verify that search ranking produces consistent, expected ordering for known test data - 4. All tests in this phase pass with `-race` flag enabled -**Plans:** 2 plans -Plans: -- [x] 05-01-PLAN.md — FTS5 search tests, pure helper tests, search index operations, migration verification -- [x] 05-02-PLAN.md — Entity cache tests, library pure helpers, orphan cleanup tests - -### Phase 6: SQL Consolidation & Code Quality -**Goal:** Duplicated SQL patterns are eliminated, event names are provably synchronized between Go and TypeScript, and intentional SQL exceptions are documented -**Depends on:** Phase 5 (FTS5 search tests verify consolidation doesn't break ranking; database tests verify migration safety) -**Requirements:** QUAL-01, QUAL-02, QUAL-03, QUAL-04 -**Success Criteria** (what must be TRUE): - 1. The duplicated 5-table FTS5 JOIN pattern is consolidated into a single SQLite VIEW (`track_metadata` or similar), and all search queries use the VIEW instead of inline JOINs - 2. A code generator reads Go event constants from `backend/events/events.go` and produces `frontend/src/events.ts`, wired into `go generate` and the pre-commit hook — adding an event in Go without regenerating TypeScript fails the hook - 3. Queue batch lookups in `persistence.go` use `sqlc.slice()` for IN clauses where sqlc supports it, replacing `fmt.Sprintf` placeholder construction - 4. Every hand-crafted SQL statement that intentionally bypasses sqlc has a `// SAFETY:` comment explaining why (batch INSERT, dynamic IN clauses, etc.) -**Plans:** 3 plans -Plans: -- [x] 06-01-PLAN.md — Create track_metadata VIEW and consolidate search queries -- [x] 06-02-PLAN.md — Event codegen tool (Go→TypeScript) and pre-commit hook wiring -- [x] 06-03-PLAN.md — Migrate lookupChunk to sqlc.slice() and add SAFETY comments to all hand-crafted SQL - -### Phase 7: Backend Performance -**Goal:** Queue mutations and library loading are fast — single-track queue changes are O(1) instead of O(n), and the library doesn't block startup with a full data fetch -**Depends on:** Phase 4 (queue tests verify persistence optimization doesn't lose data), Phase 5 (library tests verify lazy loading doesn't break data access) -**Requirements:** PERF-01, PERF-02, PERF-03 -**Success Criteria** (what must be TRUE): - 1. Adding or removing a single track from the queue uses incremental INSERT/DELETE via existing sqlc queries, not a full table rewrite - 2. SetQueue Phase 2 (`resolveRemainingTracks`) skips file paths that were already resolved in Phase 1, eliminating redundant database lookups - 3. Library store constructor no longer calls `eagerFetch()` — data loads lazily on first access via the existing `getTracks()`/`getAlbums()`/etc. getters, and the app starts without blocking on a full library load -**Plans:** 2 plans -Plans: -- [x] 07-01-PLAN.md — Incremental queue persistence + SetQueue Phase 2 dedup -- [x] 07-02-PLAN.md — Library store deferred eager loading - -### Phase 8: Frontend Performance & UX -**Goal:** The app feels smooth and visually consistent — large libraries render without jank, and the UI follows a coherent visual language -**Depends on:** Phase 7 (backend lazy loading changes the data availability pattern the frontend consumes) -**Requirements:** PERF-05, UX-01, UX-02 -**Success Criteria** (what must be TRUE): - 1. Track and album lists use Lit `repeat()` directive with stable keys (filePath for tracks, albumId for albums) for efficient DOM reuse during scrolling and filtering - 2. Store notifications during rapid updates (e.g., library scan) are debounced via `queueMicrotask()` to prevent layout thrashing - 3. Visual inconsistencies (spacing, colors, typography, icon sizing) are audited and follow a consistent pattern across all components - 4. Scrolling, view switching, and search filtering in a 10k+ track library are smooth with no visible jank or dropped frames -**Plans:** 4 plans -Plans: -- [x] 08-01-PLAN.md — Store debouncing (queueMicrotask), search debounce, design token definitions -- [x] 08-02-PLAN.md — Virtualizer repeat() directive migration (all 5 components) -- [x] 08-03-PLAN.md — Track-list/queue-panel render optimization (classMap, search highlight short-circuit) -- [x] 08-04-PLAN.md — Visual consistency audit & token application across all components +

Player.SetContext() uses a single lock acquisition instead of the double-lock pattern + 4. Concurrent calls to SetContext from multiple goroutines do not corrupt shared state +**Plans:** 1 plan +Plans: +- [x] 01-01-PLAN.md — Add mutex protection to all SetContext methods and collapse Player double-lock + +### Phase 2: Backend Correctness +**Goal:** All known error handling gaps are closed, configuration is secure, and the backend reports problems honestly instead of swallowing them +**Depends on:** Phase 1 (race-free code is prerequisite for reliable error paths) +**Requirements:** CORR-05, CORR-06, CORR-07, CORR-08, CORR-09 +**Success Criteria** (what must be TRUE): + 1. The package-level `startupErr` variable no longer exists; startup errors are stored in a YellowJacketApp struct field + 2. Config files are written with 0o644 permissions (owner read/write, group/other read-only) + 3. MPRIS lifecycle callback errors (Pause, Seek) appear in the application log instead of being silently discarded + 4. Artist credit link creation checks the actual error — only UNIQUE constraint violations are ignored, all other errors are surfaced + 5. Library.Scan() returns warnings (skipped files, partial failures) in ScanMetrics and fatal errors (database failures) in the error return, so callers can distinguish between "scan completed with issues" and "scan failed" +**Plans:** 2 plans +Plans: +- [x] 02-01-PLAN.md — Fix startupErr global state, config permissions, and MPRIS callback error logging +- [x] 02-02-PLAN.md — Add IsUniqueViolation helper, migration 3, and separate scan warnings from fatal errors + +### Phase 3: Test Infrastructure +**Goal:** A reliable, production-mirroring test foundation exists so that all subsequent test phases can write database-backed tests with confidence +**Depends on:** Phase 1 (race-free code required for `-race`-clean test runs), Phase 2 (correct error handling needed for accurate test assertions) +**Requirements:** TEST-01, PERF-04 +**Success Criteria** (what must be TRUE): + 1. `database.NewTestDB(t)` returns a clean in-memory SQLite database that applies the same migrations and PRAGMAs as the production `NewDB()` + 2. Production SQLite connection applies `synchronous=NORMAL`, `cache_size=-8000`, and `mmap_size=67108864` PRAGMAs at database open + 3. Each test gets an isolated database instance — no shared state between test functions + 4. Tests using `NewTestDB` pass with `-race` flag enabled +**Plans:** 1 plan +Plans: +- [x] 03-01-PLAN.md — Extract shared applyPRAGMAs, add production PRAGMAs, and create NewTestDB helper + +### Phase 4: Queue, Config & Player Tests +**Goal:** The queue, config, and player packages have comprehensive unit tests that characterize current behavior and serve as a safety net for later refactoring +**Depends on:** Phase 3 (queue tests need NewTestDB for persistence tests) +**Requirements:** TEST-02, TEST-04, TEST-05 +**Success Criteria** (what must be TRUE): + 1. Queue package has ~15-20 tests covering SetQueue, Next, Previous, shuffle mode, repeat modes (off, one, all), and state persistence across save/load cycles + 2. Config package has ~8-10 tests covering load/save roundtrip fidelity, validation rule enforcement, default value application, and graceful handling of missing or empty config files + 3. Player pure logic (UserVolume↔Volume conversion, state serialization/deserialization, format detection from file extension) is extracted into standalone functions with ~5-8 unit tests + 4. All tests in this phase pass with `-race` flag enabled +**Plans:** 2 plans +Plans: +- [x] 04-01-PLAN.md — Queue package unit tests (core operations, navigation, persistence roundtrip) +- [x] 04-02-PLAN.md — Config + Player tests (sub-config validators, load/save roundtrip, volume conversion, state mapping) + +### Phase 5: Database & Library Tests +**Goal:** Database queries (especially FTS5 search) and library scan logic have unit tests that lock down current behavior before SQL consolidation and performance optimization +**Depends on:** Phase 3 (database tests need NewTestDB), Phase 4 (queue tests validate persistence patterns reused here) +**Requirements:** TEST-03, TEST-06 +**Success Criteria** (what must be TRUE): + 1. Database package has ~10-15 tests covering FTS5 search (basic terms, empty query, special characters, multi-word), search index rebuild, and schema migration application + 2. Library scan logic has ~10-15 tests covering metadata extraction processing, entity cache hit/miss behavior, and orphan track cleanup + 3. FTS5 search tests verify that search ranking produces consistent, expected ordering for known test data + 4. All tests in this phase pass with `-race` flag enabled +**Plans:** 2 plans +Plans: +- [x] 05-01-PLAN.md — FTS5 search tests, pure helper tests, search index operations, migration verification +- [x] 05-02-PLAN.md — Entity cache tests, library pure helpers, orphan cleanup tests + +### Phase 6: SQL Consolidation & Code Quality +**Goal:** Duplicated SQL patterns are eliminated, event names are provably synchronized between Go and TypeScript, and intentional SQL exceptions are documented +**Depends on:** Phase 5 (FTS5 search tests verify consolidation doesn't break ranking; database tests verify migration safety) +**Requirements:** QUAL-01, QUAL-02, QUAL-03, QUAL-04 +**Success Criteria** (what must be TRUE): + 1. The duplicated 5-table FTS5 JOIN pattern is consolidated into a single SQLite VIEW (`track_metadata` or similar), and all search queries use the VIEW instead of inline JOINs + 2. A code generator reads Go event constants from `backend/events/events.go` and produces `frontend/src/events.ts`, wired into `go generate` and the pre-commit hook — adding an event in Go without regenerating TypeScript fails the hook + 3. Queue batch lookups in `persistence.go` use `sqlc.slice()` for IN clauses where sqlc supports it, replacing `fmt.Sprintf` placeholder construction + 4. Every hand-crafted SQL statement that intentionally bypasses sqlc has a `// SAFETY:` comment explaining why (batch INSERT, dynamic IN clauses, etc.) +**Plans:** 3 plans +Plans: +- [x] 06-01-PLAN.md — Create track_metadata VIEW and consolidate search queries +- [x] 06-02-PLAN.md — Event codegen tool (Go→TypeScript) and pre-commit hook wiring +- [x] 06-03-PLAN.md — Migrate lookupChunk to sqlc.slice() and add SAFETY comments to all hand-crafted SQL + +### Phase 7: Backend Performance +**Goal:** Queue mutations and library loading are fast — single-track queue changes are O(1) instead of O(n), and the library doesn't block startup with a full data fetch +**Depends on:** Phase 4 (queue tests verify persistence optimization doesn't lose data), Phase 5 (library tests verify lazy loading doesn't break data access) +**Requirements:** PERF-01, PERF-02, PERF-03 +**Success Criteria** (what must be TRUE): + 1. Adding or removing a single track from the queue uses incremental INSERT/DELETE via existing sqlc queries, not a full table rewrite + 2. SetQueue Phase 2 (`resolveRemainingTracks`) skips file paths that were already resolved in Phase 1, eliminating redundant database lookups + 3. Library store constructor no longer calls `eagerFetch()` — data loads lazily on first access via the existing `getTracks()`/`getAlbums()`/etc. getters, and the app starts without blocking on a full library load +**Plans:** 2 plans +Plans: +- [x] 07-01-PLAN.md — Incremental queue persistence + SetQueue Phase 2 dedup +- [x] 07-02-PLAN.md — Library store deferred eager loading + +### Phase 8: Frontend Performance & UX +**Goal:** The app feels smooth and visually consistent — large libraries render without jank, and the UI follows a coherent visual language +**Depends on:** Phase 7 (backend lazy loading changes the data availability pattern the frontend consumes) +**Requirements:** PERF-05, UX-01, UX-02 +**Success Criteria** (what must be TRUE): + 1. Track and album lists use Lit `repeat()` directive with stable keys (filePath for tracks, albumId for albums) for efficient DOM reuse during scrolling and filtering + 2. Store notifications during rapid updates (e.g., library scan) are debounced via `queueMicrotask()` to prevent layout thrashing + 3. Visual inconsistencies (spacing, colors, typography, icon sizing) are audited and follow a consistent pattern across all components + 4. Scrolling, view switching, and search filtering in a 10k+ track library are smooth with no visible jank or dropped frames +**Plans:** 4 plans +Plans: +- [x] 08-01-PLAN.md — Store debouncing (queueMicrotask), search debounce, design token definitions +- [x] 08-02-PLAN.md — Virtualizer repeat() directive migration (all 5 components) +- [x] 08-03-PLAN.md — Track-list/queue-panel render optimization (classMap, search highlight short-circuit) +- [x] 08-04-PLAN.md — Visual consistency audit & token application across all components + +## Progress + +| Phase | Plans Complete | Status | Completed | +|-------|----------------|--------|-----------| +| 1.

Add 8px + 8px vertical padding = 47px. Plus 1px border-bottom = 48px total box. Setting `height: 49px` gives 1px breathing room for sub-pixel rounding (the `border-bottom` is outside the height due to `box-sizing: border-box` including it — actually border-box INCLUDES the border in height, so 49px = 8px pad-top + ~32px content + 8px pad-bottom + 1px border = 49px total). + +**IMPORTANT:** After setting this, verify the actual rendered height matches by loading the app with a queue of tracks and inspecting a `.track-item` in DevTools.

Inconsistent communication patterns: queue (events) vs playlist (bindings) - -**Problem:** Queue operations use 14+ `Request*` events with manual `data[0].(type)` casting in ~300 lines of handler boilerplate. Playlist operations use direct Wails bindings with type-safe Go function signatures. - -**Why it matters:** Inconsistency makes the codebase harder to learn. The queue's event-only approach requires substantial boilerplate that the playlist avoids. New features on the queue require touching 4 files (Go event constant, TS event constant, Go handler, TS store method) vs 1-2 files for the playlist. - -**Approach:** This is a larger refactor. Two options: - -1. **Move queue to bindings** (recommended): Add the queue to `FEBindings`, expose typed methods, call them directly from the frontend store. Remove the event handlers and the `Request*` events. Keep the backend-to-frontend events (`QueueChanged`, etc.) for state push. -2. **Accept the inconsistency**: Document the rationale (queue existed before playlists, events were the original pattern, bindings were adopted later). Add a comment in AGENTS.md. - ---- - -## P3 — Fix opportunistically - -### 13. Dead player methods: `ChangeVolume`, `MuteToggle`, `CurrentPosition` - -**Problem:** `ChangeVolume()` (`player.go`), `MuteToggle()` (`player.go`), and `CurrentPosition()` (percentage-based, `player.go`) have zero callers anywhere in the codebase. - -**Approach:** Delete them, or keep them if you plan to add keyboard shortcuts / media key support soon. - ---- - -### 14. ~~Unused queue sentinels: `ErrEmptyQueue`, `ErrNoPlayer`~~ — solved - ---- - -### 15. `SeekFailed` event emitted but never listened to - -**Problem:** `player.go` emits `SeekFailed` when seeking fails, but no frontend code subscribes to it. Users get no feedback on seek failure. - -**Approach:** Either add a frontend listener that shows a brief notification/toast, or remove the event emission if seek failure feedback isn't needed. - ---- - -### 16. `path.Join` instead of `filepath.Join` in config - -**Problem:** `config/config.go:41` uses `path.Join` (POSIX paths) instead of `filepath.Join` (OS-aware paths) for constructing the config file path. - -**Approach:** Replace with `filepath.Join`. Single-line change. - ---- - -### 17. Replace 200ms sleep with frontend-ready handshake - -**Problem:** `app.go:205-216` uses `time.Sleep(200 * time.Millisecond)` before emitting state to the frontend, assuming it will be ready by then. - -**Approach:** Have the frontend emit a "ready" event when its stores have initialized. The backend listens for this event and then emits the current state. Eliminates the timing assumption. - ---- - -### 18. ~~Custom `sortInts` in queue instead of `slices.Sort`~~ — solved - -Replaced during the queue.go refactoring (item #3). - ---- - -### 19. `playlist-picker.ts` bypasses `playlistStore` - -**Problem:** `playlist-picker.ts` calls `GetAllPlaylists()` directly from the Go binding instead of going through `playlistStore`. It fetches only summaries (not `WithTracks`), which is why it doesn't use the store. - -**Approach:** Either add a `getSummaries()` method to the playlist store that caches just the summary list, or accept this as intentional since the picker only needs summaries and the full `WithTracks` fetch would be wasteful for this use case. - ---- - -### 20. `library-manager.ts` and `config-page.ts` overlap - -**Problem:** Both components exist (different nav routes: "libraries" vs "settings"). `config-page.ts` has a comment saying scan metrics were "carried over from library-manager". They may have diverging copies of similar logic. - -**Approach:** Audit both components for duplicated logic. If the library manager's functionality is fully subsumed by the config page, consider removing it and redirecting the "libraries" nav route.
